Short answer

An investigator wanted to construct a 95% confidence interval estimate for the mean of a given population. He took a simple random sample of size n, as indicated above, and constructed a confidence interval of ( -9.2 , 17.4 ) according to the methods  (1meanT) indicated in class. What was the ( approximate ) probability  that the investigator's procedure would produce an interval that would capture/surround the mean of the given population? (The histogram for the sample is given above.)   If it is not possible to answer this, enter -1. c07.p061.q010

Step-by-Step Analysis
To start, recall what a 95% confidence interval means in the context of repeated sampling. If we were to take many random samples of the same size from the population and construct a 95% CI from each sample using the same method, about 95% of those intervals would contain ......Login to view full explanation

Some fast-food chains offer a lower-priced combination meal in an effort to attract budget-conscious customers. One chain tested a burger, chips and drink combination for $6.95. The weekly sales volume for these meals was impressive. Suppose the chain wants to estimate the average amount its customers spent (in dollars) on a meal at their restaurant while this combination offer was in effect. An analyst gathers data from 28 randomly selected customers. The following data represent the sample meal totals in dollars. The average spending from the sample is $7.87 and the sample standard deviation is $0.87.   Use the above information to construct a 90% confidence interval( Upper and lower Limit )  to estimate the population mean value in dollars. Assume that the amounts spent are normally distributed.

A random sample of 10 VISA cardholder accounts revealed a sample mean debt of $1,120 with a sample standard deviation of $340. Construct a 95% per cent confidence interval estimate of the average debt of all cardholders.   This calculation can not be performed  

A popular restaurant takes a random sample n = 25 customers and records how long each occupied a table. They found a sample mean of 1.2 hours and a sample standard deviation of 0.3 hours. Find the 95 percent confidence interval for the mean.

In an effort to estimate the mean dollars spent per visit by customers of a food store, the manager has selected a random sample of 100 cash register receipts. The mean of this random sample was $45.67 with a sample standard deviation equal to $12.30. Assuming that he wants to develop a 90 percent confidence interval estimate, the upper limit of the confidence interval estimate is:
