STAT 2002 Walden University Week 1 Classify Statistical Scenarios Questions
Consider the following questions:How much does milk cost on the East Coast of the United States? How many minutes does it take to drive 30 miles at an average speed of 55 miles per hour?What is the age difference between you and your siblings?How many hours of sleep do teenagers get during the school year compared to summer vacation?Define each question as being or not being a statistical question and explain why. (75–150 words, or 1–2 paragraphs)Joan Horton is a building contractor whose company builds many homes every year. In planning for each job, Joan needs some idea about the direct labor hours per square foot required to build a home. She has collected sample information on the labor hours for 10 jobs during the past year. (300 words, or 4 paragraphs) Job12345678910Hours245291353118152402351242595173Calculate the mean for this sample. How can Joan use this information?Calculate the median from this sample. If Joan had to select the mean or the median as the estimate of direct labor hours, what factors about each statistic should she consider before making the decision?Calculate the sample variance and standard deviation. How can Joan use these values in planning future jobs?One of Joan’s competitors, J.M. Sawyer, has numbers claiming that his crews average 350 hours per square foot, with a standard deviation of 50. Sawyer further claims that his company is more consistent in direct labor hours applied to houses than Horton’s company. Who is right, and why?The weekly total of hours for the servers and the cooks for a small restaurant are listed below. Find the range, variance, and standard deviation for each set.

#4) A large number of people were polled and asked which of four different animals were their favorite. 13% said Penguin, 21% said Iguana, 22% said Parrot, and 44% said Turtle. Suppose you decide to carry out a simulation given these percentages. You decide to select two digits at a time. Which would be a proper assignment of digits for these teams?
a) 01-13 = Penguin, 01-21 = Iguana, 01-22 = Parrot, 01-44 = Turtleb) 00-13 = Penguin, 14-34 = Iguana, 35-56 = Parrot, 57-99 = Turtlec) 01-13 = Penguin, 14-35 = Iguana, 36-58 = Parrot, 59-99 & 00 = Turtled) 01-13 = Penguin, 14-34 = Iguana, 35-56 = Parrot, 57-99 & 00 = Turtlee) None of These
#5) The expected value for the following scenario is $1.60. Write two different equations that give both a simplified equation using the expected value and a simplified equation for the total of all probabilities in the probability model.
Value $3 -$4 $17Probability x y 0.08
#6) Suppose that there are 513 students who are currently enrolled in AP Calculus and that we are looking for five randomly selected students to survey about their experiences in AP Calculus. The digit combinations 001-513 are assigned to represent the 513 students currently enrolled in AP Calculus. Using the random digits below, what are the numbers of the five students that will be selected for the survey? 71548 15233 53946 68713 72468 27601 13703 88692
Student 1 = #_____, Student 2 = #_____, Student 3 = #_____, Student 4 = #_____, Student 5 = #_____
#7) If you buy a ticket in a certain lottery game, 30% of the players will get paid $1, 20% of the players will get paid $6, and 5% of the players will get paid $55. All other players get paid nothing. What is the expected amount that a player of this lottery game will get paid?
#8) In a certain card game you draw one card off a standard deck of 52 cards. If you draw a spade you get paid $12, if you draw a red Ace you get paid $20, and if you draw a red Queen you get paid $38. If you draw anything else, you get paid nothing. What should this game cost if it is to be a fair game? Use fractions in your work and then calculate the answer as a decimal rounded to 4 decimal places.

University of Maryland Decisions About Alpha Level Related to Sciences Paper
Decisions about alpha level may be different, especially as it relates from hard sciences to social sciences. For example, a medical trial for cancer treatments conducts their statistical tests at .0001 – so for every 1 out of 10,000 patients, there may be issues, sickness or even death. For social science, we use alpha .05. We are comfortable with performing research, for example, on students. So we are satisfied with losing 5 out of 100 students or having our results being incorrect 5 out of 100 times. Do you agree with these alpha levels? Why or why not? What if your child’s education and the teacher assigned to him/her would be successful 95 out of 100 times?
