Express your answer as a decimal, statistics homework help
7.A radar unit is used to measure speeds of cars on a motorway. The speeds are normally distributed with a mean of 90 km/hr and a standard deviation of 10 km/hr. What is the probability that a car picked at random is travelling at more than 100 km/hr? Round your answer to the nearest thousandth.8.A survey by the National Retail Federation found that women spend on average $146.21 for the Christmas holidays. Assume the standard deviation is $29.44. Find the percentage of women who spend less than $160.00. Assume the variable is normally distributed. Express the answer in the form of a percentage (do not include % sign in your answer). Round your answer to the nearest hundredth.9.Each month, an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds. If a household is selected at random, find the probability of its generation between 27 and 31 pounds per month. Assume the variable is normally distributed. Express your answer as a percentage. (do not include % sign in your answer). Round your answer to the nearest hundredth10.The national average SAT score (for Verbal and Math) is 1028. If we assume a normal distribution with standard deviation 92, what is the probability that a randomly selected score exceeds 1200? Express your answer as a decimal. Round your answer to the nearest hundredth.11.To qualify for a police academy, candidates must score in the top 10% on a general abilities test.

Survey Information Links https://www.surveymonkey.com/results/SM-RBM2J2FX7/https://www.surveymonkey.com/results/SM-J5BKC2FX7/Research Focus:how creating health programs for children and parents in middle school lead to decreasing the consumption of tobacco in teenagersPurpose of research:Tobacco smoking in the country is the primary source of preventable death. Many smokers (82 percent) began to smoke before 18, and about 3,000 young people continue to smoke every day. School initiatives to discourage the usage of cigarettes may become one of the most successful nicotine approaches implemented. This survey seeks to identify whether creating health programs for children and parents in middle school lead to decreasing the consumption of tobacco in teenagers. The survey will determine whether the reduced use of tobacco among teenagers (dependent variable) is directly challenged by the health programs put in place in middle schools (independent variable). This survey will target teenage students as well as parents in middle school and consequently summarize their feedback regarding the issue. AssignmentBy this week, you should have completed data collection on at least 30 participants who met the qualifications to complete the survey (e.g., at least 18 years or older, have other specific characteristics that make them a member of the population you intended to study).The data for your short survey should be entered into the Excel database that you created last week. With this data set, complete the following:Calculate descriptive statistics for your main independent and other variables you have collected information on (example: demographic variables).Create a bar chart for the participants’ gender and ethnicity.Create a histogram for participants’ age. Calculate descriptive statistics for your dependent variable. Create a summary table of your descriptive statistics.Hint: For categorical variables, you should be calculating frequencies and percentages; for continuous variables, you should be calculating means and standard deviations.Use one hypothesis-testing statistic that examines the relationship between your independent variable and dependent variable.Hint: This test should be one of the following—independent samples t-test, paired t-test, one-way ANOVA, or Pearson’s chi-squared test.Write the null and alternate hypotheses.What is the calculated statistic value?What is the p and critical statistic value?Is the p value significant? Is calculated statistic value greater than critical value?What is your conclusion?

University of San Diego Technology Enabled Operations Analysis
Hi, I need someone to help for my Technology-Enabled Operations class homework. I have attached the file. Thank you Wendy's Wonder Wagons Wendy's Wonder Wagons manufactures brightly-colored, battery-powered wagons that will be scattered about the streets of cities to allow people to haul groceries, dogs, and small children. Below is a simplified process flow diagram for production of the wagons. Forming Coating Assembly 20 min (batch of 10 min 1_4 units) 15 min The forming machine takes 10 minutes to convert plastic pellets into a wagon body. The coating machine takes 20 minutes, and it spray coats (with a single color) up to four wagon bodies simultaneously. Wagon bodies then go to a drying room (with plenty of space) and air dry for 3 hours. Assembly takes 15 minutes to attach the wheels, power unit, and handle. Cross-trained workers are available so we don't need to worry about labor scheduling. We'll focus on steady state and not concern ourselves with start-up and shut down — you can assume the production system operates non-stop, 24 hours a day, 7 days a week. Currently, Wendy's Wonder Wagons is making one unit of each color at a time — e.g., a lime green wagon, then an iridescent puce wagon, then a luminous red wagon, etc. Assume they are running at full capacity. A. Base Case (steady-state, running at full capacity) a. What is the bottleneck task? b. What is the capacity of the production process, in wagons per 24-hour day? c. What is the throughput time? d. What is the average number of wagon bodies in the drying room? B. Wendy would like to increase capacity. She wants you to evaluate the proposals below. For each, indicate the resulting production capacity (in wagons per 24-hour day), and the throughput time. Briefly indicate why it has changed (or not changed) from the base case. Be sure to provide any calculations you made. a. Acquire a second forming machine b. Increase the batch size of the coating machine to 6 units, continuing to produce 1 unit of each color at a time. c.Produce wagons in batches of 4 (i.e., 4 sunshine yellow, then 4 ornery orange, etc.) d. Use a fast-drying coating material so the wagon bodies dry in only 10 minutes
