What can be concluded at the the αα = 0.01 level of significance level of significance?
- For this study, we should use Select an answer t-test for a population mean z-test for a population proportion
- The null and alternative hypotheses would be:
H0:H0: ? μ p Select an answer > ≠ < =
H1:H1: ? p μ Select an answer > < ≠ =
- The test statistic ? t z = (please show your answer to 3 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
- The p-value is ? > ≤ αα
- Based on this, we should Select an answer reject accept fail to reject the null hypothesis.
- Thus, the final conclusion is that ...
- The data suggest that the population mean wait time for men who wear a tie is not significantly different from 7 at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is different from 7.
- The data suggest the population mean is not significantly different from 7 at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is equal to 7.
- The data suggest the populaton mean is significantly different from 7 at αα = 0.01, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is different from 7.

- Citrus Rental is a popular car rental agency that has a history of having too few cars available, so that its available cars are overdriven. The mean monthly mileage over the years for Citrus cars has been about 1550 miles per month. Recently, though, Citrus purchased thousands of new cars, and the company claims that the average mileage of its cars is now less than in the past. To test this, a random sample of 15 recent mileages of Citrus cars was taken. The mean of these 15 mileages was 1517 miles per month, and the standard deviation was 201 miles per month. Assume that the population of recent monthly mileages of Citrus cars is normally distributed. At the 0.05 level of significance, can it be concluded that the mean recent monthly mileage, μ, of Citrus cars is less than 1550 miles per month? Perform a one-tailed test. Then complete the parts below.arrow_forwardA random sample of patient records from a large medical facility were taken and subjects were classified by smoking status and cholesterol levels.

- A national nursing organization is lobbying congress for sunding to hire more nurses nationwide. One of the arguments is that nurses, on average, work significantly longer than full time duty, assuming full time is 40 hours a week.

Researchers working for a sports drink company would like to know if a new blend if its popular sports drink can help improve marathon runners' final running time. Marathon times, Y, are known to follow a Normal distribution. Suppose that runners using the old blend sports drink have a mean finishing time of 300 minutes (H = 300 minutes). A random sample of 20 runners was selected to use the new blend of sports drink in a marathon, finishing with an average time of 270 minutes and a standard deviation of 20 minutes (y = 270 min, s = 20 min). Can it be claimed that the new blend lowers finishing times? Or is it possible that random chance alone can explain the discrepancy?

The mean shopping time, μ , spent by customers at the supermarkets has been reported to be 36 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that μ is greater than 36 minutes. The consultant plans to do a statistical test and collects a random sample of 50 shopping times at the supermarkets.
