The average student-loan debt is reported to be $25,235. A student believes that the student-loan debt is higher in her area. She takes a random sample of 100 college students in her area and determines the mean student-loan debt is $27,524 and the standard deviation is $6,000. Is there sufficient evidence to support the student's claim at a 5% significance level? Preliminary: a. Is it safe to assume that n < 5% of all college students in the local area? O Yes No b. Is n 2 30 ? O Yes No Test the claim: a. Determine the null and alternative hypotheses. Enter correct symbol and value. Ho: H Ha: µ ? V b. Determine the test statistic. Round to two decimals. t = c. Find the p-value. Round to 4 decimals. p-value = %3D d. Make a decision. Reject the null hypothesis. Fail to reject the null hypothesis. e. Write the conclusion. There is not sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.

A manufacturer claims that only 2% of their products are defective. A store receives a delivery of 300 items from the manufacturer. Let p-hat = the proportion of defective items in a sample of 300 items. Assuming the manufacturer is correct that only 2% of their products are defective, what are the mean and standard deviation of the sampling distribution of p-hat ? Options: The mean is 0.02 and the standard deviation is 0.008. The mean is 6 and the standard deviation is 2.42. The mean is 6 and the standard deviation is 5.88. The mean is 0.02 and the standard deviation is 0.196.
A marketing researcher wants to estimate the mean amount spent ($) on a certain retail website by members of the website's premium program. A random sample of 93 members of the website's premium program who recently made a purchase on the website yielded a mean of $1200 and a standard deviation of $150. Complete parts (a) and (b) below. a. Construct a 95% confidence interval estimate for the mean spending for all shoppers who are members of the website's premium program. |5με (Round to two decimal places as needed.)

A national grocer's magazine reports the typical shopper spends 11 minutes in line waiting to check out. A sample of 21 shoppers at the local Farmer Jack's showed a mean of 10.0 minutes with a standard deviation of 2.2 minutes. Is the waiting time at the local Farmer Jack's less than that reported in the national magazine? Use the 0.050 significance level. a. What is the decision rule? (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Reject 10 p2 11 and fall to reject 11 11 when the test statistic is b. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)
A certain beverage company is suspected of underfilling its cans of soft drink. The company advertises that its cans contain, on the average, 12 ounces of soda with a standard deviation of 0.4 ounces (which is, in fact, the truth). A quality control inspector measures the contents of an SRS of 50 cans of the company's soda. A. The mean of the sampling distribution of sample means. B. The standard deviation of the sampling distribution of sample means. C. Describe the shape of the sampling distribution of sample means. Justify your answer. D. Calculate the probability that the average fill of the soda cans is 11.9 ounces or less. Please show all work for full credit (sketch the curve, z-score, etc.).

Which is cheaper: eating out or dining in? The mean cost of a steak, salad, and rice bought at the grocery store is $13.04. A sample of 30 neighborhood restaurants showed a mean price of $12.15 and a standard deviation of $2 for a comparable restaurant meal. 1.1) Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean cost of a restaurant meal is less than $13.04. 1.2) At alpha = 0.05, what is your conclusion?
