A software company markets a new computer game with two experimental packaging designs. Design 1is sent to 11 stores and their average sale the first month is 52 units with sample standard deviation 12 units.Design 2 is sent to 6 stores and their average sale the first month is 46 units with sample standard deviation10 units.a. Compute and interpret a point estimate for the difference in average monthly sales between the twopackage designs.b. Construct and interpret a 95% confidence interval for the difference in average monthly sales betweenthe two package designs.

A healthcare information company is interested in estimating the average charge for a standard patient visit to a chiropractor in Maryland, after applying the discount negotiated with a large HMO plan. Data is collected from 16 randomly selected chiropractic practices in Maryland, and the following are some summary statistics:- Mean charge: 25.50 USD- SD of charges: 2.10 USDAssuming the charge data is normally distributed for all chiropractic practices in Maryland, estimate a 95% confidence interval for the mean amount charged by Maryland chiropractors (t (15, 0.05) = 2.13):
Suppose that a safety group surveyed 1,100 drivers. Among those surveyed, 65% said that careless or aggressive driving was the biggest threat on the road, and 25% said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a 95% confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users. The confidence interval estimate is ??––––––??> (Round to three decimal places as needed. Use ascending order.) Interpret the confidence interval estimate. A. There is a 0.95 probability that the population proportion of drivers who are annoyed by cell phone users is in the interval. B. There is 95% confidence that the population proportion of drivers who are annoyed by cell phone users is in the interval. C. There is 95% confidence that the population proportion…
Suppose an economist wishes to estimate the mean commute time of workers in Westchester County. The economist obtains a random sample of 31 commutes in Westchester County and finds the sample mean to be 31.2 minutes and the sample standard deviation to be 12.1 minutes. a. Construct and interpret a 90% confidence interval for the mean commute time in Westchester County. b. Construct and interpret a 95% confidence interval for the mean commute time in Westchester County.
In a situation where the sample size was decreased from 39 to 29 in a normally distributed data set, what would be the impact on the confidence interval?
An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 339 people living in East Vancouver and finds that 40 have recently had the flu. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of East Vancouver residents who have recently had the flu. A. 11.80% (40/339) of East Vancouver residents have recently had the flu. ? true false B. There is a 95% probability that the true proportion of East Vancouver residents who have recently had the flu equals 40/339. ? true false C. If another random sample of 339 East Vancouver residents is drawn, there is a 95% probability that the sample proportion of East Vancouver residents who have recently had the flu equals 40/339. ?…
A research group studying cell phone habits asked the question “Do you ever use your cell phone to make a payment at a convenience store?” to people selected from two random samples of cell phone users. One sample consisted of older adults, ages 35 years and older, and the other sample consisted of younger adults, ages 18 years to 34 years. The proportion of people who answered yes in each sample was used to create a 95 percent confidence interval of (0.097,0.125)(0.097,0.125) to estimate the difference (younger minus older) between the population proportions of people who would answer yes to the question. Which of the following is the best description of what is meant by 95 percent confidence? In repeated random sampling with the same sample size, approximately 95% of the sample proportions from the younger group will be between 0.097 and 0.125 greater than the sample proportion from the older group. A In repeated random sampling with the same sample size,…
2)The manager for a contractual ride-share company wants to construct a control chart for determining whether 10-drivers are under control with regard to the number of complaints filed. Accordingly, the manager sampled 100 reviews from last year for each driver, with the following results: Driver Number of Complaints 1 8 2 18 3 21 4 6 5 17 6 15 7 19 8 5 9 23 10…
2. A food truck serves lunch every Tuesday and Thursday on the plaza in front of Van Metre Hall on the GMU Arlington campus. The number of customers varies every day, so it wants to order supplies based on the average number of customers served per day. The truck recorded how many customers were served on 40 randomly selected days, and obtained a sample mean and sample standard deviation of 145 and 17, respectively. Construct a 90% confidence interval for the mean number of customers served per day.
1) Using the data table, find and report the following probabilities: a. The probability that one randomly selected patient is experiencing High CoVID-19 severity given they are a Never Smoker b. The probability that one randomly selected patient is experiencing High CoVID-19 severity given they are an “Ever” Smoker meaning that they are a Current or Former Smoker, 2) Using StatCrunch* and the available data, construct a 99% Confidence Interval for the proportion of all patients experiencing High CoVID-19 severity if they are a Never Smoker. a. Report the confidence interval using proper notation. b. In one to two complete sentences, state an interpretation for this confidence interval. 3) Using StatCrunch* and the available data, construct a 99% Confidence Interval for the proportion of all patients experiencing High CoVID-19 severity if they are an “Ever” Smoker (i.e., they are a Current or Former Smoker. a. Report the confidence interval using proper notation. b. In one to two…

A U.S. Food Survey showed that Americans routinely eat beef in their diet. Suppose that in a study of 49 consumers in Illinois and 64 consumers in Texas the following results were obtained from two samples regarding average yearly beef consumption: Illinois Texas = 49 = 64 = 54.1lb = 60.4lb S1 = 7.0 S2 = 8.0 Develop a 95% confidence Interval Estimate for the difference between the two population means.
