MATH 114 Liberty University Appliance Power Consumption Worksheet
Project 2 Instructions Please also pay close attention to any additional specifications provided by your professor. Professors often will clarify their expectations regarding the format and presentation of your submission. Ever wonder how your electricity bill is computed? The following table gives the watts of power that are typically required by several major (and not so major) appliances. (Source: http://www.wholesalesolar.com/solar-information/how-to-save-energy/power-table, with some numbers rounded off for computational convenience.) Table 1: Appliance Central Air Conditioner Water Heater Clothes Dryer Oven Dishwasher Fridge Ceiling Fan LCD TV Watts 9000 5000 4500 4000 2400 2200 220 250 Assume that the number of hours that the aforementioned appliances run during an average day is given in the table below: Table 2: Appliance Central Air Conditioner Water Heater Clothes Dryer Oven Dishwasher Fridge Ceiling Fan LCD TV Hours 5 3 3.5 2 2.5 8 13 6 Add columns to the Project 2 Data spreadsheet that show the following for each appliance: The number of kilowatts of power required by each of these appliances (1 kilowatt = 1000 watts).If the appliance runs the number of hours specified in Table 2, compute the kilowatt-hours (kWh) of energy that each appliance consumes during an average day. Note: kWh are found by multiplying the power of an appliance by the number of hours that it is in use. The number of kilowatt-hours used by each appliance in the entire YEAR.Assuming that electricity costs $0.13 per kWh, find the electricity cost of running each appliance for the entire year.According to the US Energy Information Administration (see “How much coal, natural gas or petroleum is used to generate a kilowatt-hour of electricity” on https://www.eia.gov/tools/faqs/), it requires 0.00052 tons of coal to generate 1 kWh of electricity. Use this conversion to find how much coal would be required to run each of these appliances for a year.The same source also states that 0.00173 barrels of oil will generate 1 kWh of electricity. Like question 5, find how much oil each appliance would consume on an annual basis.Add a “Total” row to the spreadsheet that shows how much electricity is consumed by all 8 appliances combined in the course of a day and of a year. Also, find the cost, the amount of coal that would be required, and the barrels of oil that would be required in order to run all 8 appliances for a year.

RES-845 Module 4 SPSS Data Interpretation
Details:A related samples t-test compares the mean values of two related samples. In this assignment, you will review the SPSS output for a related samples t-test and use it to answer questions about the means of the two related samples.General Requirements:Use the following information to ensure successful completion of the assignment:Review "SPSS Access Instructions" for information on how to access SPSS for this assignment.Download “SPSS Data Set Legend" for use with this assignment.Download “Module 4 SPSS Output" for use with this assignment.Directions:Review the SPSS output file that reports the results of the related samples t-test to compare the number of U.S. states where each brand was sold in 2008 with the number of U.S. states where those same brands were sold in 2012. For each brand, there is one value for the number of states in 2008 and another value for the number of states in 2012, making this a repeated measure. Answer the following questions based on your observations of the SPSS output file:What was the mean number of U.S. states in which all of the beer brands were sold in 2008?What was the mean number of U.S. states in which all of the beer brands were sold in 2012?Was there a significant difference in the number of states in which these beer brands were sold in 2008 versus 2012? Report the results of the t-test as follows: t(df value) = ___, and p-value.Please complete the assignment as required and please use the appropriate references , if applicable, and cite in APA 6th edition format.

1. The following is suppose to represent probability distribution table. What is the missing value?XP(X)30.450.59?2. Find the expected value of X using the table below.XP(X)00.410.3─10.33. If the standard deviation of a random variable is 5,what is its variance?4. Any normal distribution iscontinuousdiscrete5. some are discrete, some are continuousa binomial distribution6. is Poisson distribution5. Let X be a binomial random variable with number of trials 100 and expected value 20. What is the probability of success of X?6. There are 17 blue, 5 green, and 3 red balls in a jar. We randomly select a ball and return it back to the jar. We repeat it 8 times. To find the probability of the event that every time we get a green ball we need to use the following distribution:binomial with number of trials 8 and probability of success 0.2binomial with number of trials 25 and probability of success 0.5binomial with number of trials 5 and probability of success 0.2binomial with number of trials 8 and probability of success 0.8binomial with number of trials 8 and probability of success 1/3Poisson Distribution with average 5Poisson Distribution with average 8binomial with number of trials 25 and probability of success 0.27. The average number of homes with 3 or more bedrooms sold by Acme Reality is 14 homes per week. To find the probability that exactly 3 such homes will be sold tomorrow we need to use the following distribution:Poisson distribution with mean 2Poisson distribution with mean 14Poisson distribution with mean 7Poisson distribution with mean 3Binomial with number of trials 7 and probability of success 2/7Binomial with number of trials 2 and probability of success 2/7Binomial with number of trials 7 and probability of success 1/7Standard normal distribution8. A random variable X assumes values 1,2,3,..., 8,9,and 10, each with the same probability, namely the probability 0.1. Find the probability of X getting at least 3.9. A random variable X assumes values 1,2,3,..., 8,9,10, each with the same probability, namely the probability 0.1. Find the probability of X getting no more than 4.10. A card is drawn, with replacement, from a regular deck of cards 16 times. Let random variable X represent number of clubs among those 16 cards selected (there are 13 clubs in every deck; there are 52 cards in a deck). Find the variance of X,11. The length of life of an instrument produced by a machine has a normal distribution with a mean of 12 months and standard deviation of 2 months.

Find how long an instrument that separates the bottom 83.398% will last? Round to the nearest hundredth.14. The length of life of an instrument produced by a machine has a normal distribution with a mean of 12 months and standard deviation of 2 months. What is the probability that the average number of months that these 100 instruments will last is greater than 12.2 months? Round to the nearest thousandth.15. A die is rolled 360 times.

If you want to use normal approximation to find the probability that the number of 4 was rolled at least 20 times,what is the standard deviation of the normal distribution that you would use in this case17. A die is rolled 360 times. Let say that you want to use normal approximation to find the probability that the number of 4 was rolled less than 100 times. You need to find the probability that X<100. Explain how you would use continuity correction in this case.18. A die is rolled 360 times. Let say that you want to use normal approximation to find the probability that the number of 4 was rolled exactly 100 times. You need to find the probability that X=100. Explain how you would use continuity correction in this case.19. What is the name of the theorem that states that the sampling distribution of the sample mean is approximately normal when the sample is large?20. Determine whether the following random variables have a binomial distribution:A) Ten students are chosen from a statistics class (with replacement) of 400 students.
