Suppose that a student collects sample data on how long (in minutes) it takes students to be helped at the financial aid office.A) Based on the sample data, the student finds a sample mean of 7.6 minutes and a margin or error of 1.6 minutes and calculates a 95%confidence interval to be (6.0, 9.2). Interpret what this means in context.3.B) The financial aid office claims their mean wait times are less than 8 minutes. Do you think this confidence interval provides sufficient evidencethat the mean wait time is less than 8 minutes? Explain.

Here's, mean is 7.6 and margin of error is 1.6. And confidence interval is ( 6.0, 9.2 ).

Answered: Suppose that a student collects sample…

It is calculated that, in order to estimate the true mean amount of money spent on textbooks this semester by U of M students to within $40 with 99% confidence, we need a sample of 100 students. What sample size would be required to estimate the true mean amount of money spent on textbooks to within $10 with 99% confidence?
4. A fire extinguisher salesman would like to estimate the mean number of home fires started by candles each year. He obtained fire data for seven randomly selected years from the National Fire Protection Agency. His sample produced a mean of 7041 fires with a standard deviation of 1600. Create the 90% confidence interval of interest.
8. A confidence interval for estimating the mean An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “How many work-related emails do you receive during a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 36.7 emails, with a sample standard deviation of s = 23.8 emails. The estimated standard error is sMM? = A-0.085, B-1.341, C-0.095 or D-1.505 (choices to choose from.) . Use the following Distributions tool to develop a 90% confidence interval estimate of the mean number of work-related emails legal…
5. A researcher constructed a 95% confidence interval for the true mean number of years students take to earn a bachelor's degree. His results were (4.319, 4.841). a. What is the point estimate for the average number of years to complete a bachelor's degree? b. Does his interval support or contradict the widely held belief that it takes 4 years to complete a bachelor's degree? Why or why not?
2. A common claim is that garlic lowers cholesterol levels. In a test of the effectiveness of garlic, 49 subjects were treated with doses of raw garlic, and their cholesterol levels were measured before and after the treatment. The changes in their levels of LDL cholesterol have a mean of 0.4 and a standard deviation of 21. Use the sample n = 49 to construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. n=49₁ x=0,4₁ 5=21₁ CL = 95%, df=n-1 df=49-1=48
27. In a random sample of six mobile devices, the mean repair cost was $65.00 and the standard deviation was $14.00. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 90% confidence interval for the population mean. Interpret the results.
The data below give the wait time in seconds for a random sample of callers when calling a local pizza restaurant. {66, 37, 4, 47, 12, 16, 62, 12, 21, 25, 49, 3} a. What is the point estimate for the average wait time for callers? b. Verify conditions for using this sample to predict population mean of wait times. Estimate the mean wait time for all callers to this restaurant, with 90% confidence. Write your answer as a sentence. C. d. Estimate the standard deviation of wait times for all callers to this restaurant, with 90% confidence. Write your answer as a sentence. (You do not need to check requirements.)
Suppose a sample of 9 customers spends an average of $200 with a standard deviation $20 what is a 95% confidence interval for the sample mean. Use the fact that 95% of sample means are within 2.306 standard errors of the sample mean.
