Currently patrons at the library speak at an average of 61 decibels. Will this average increase after the installation of a new computer plug in station? After the plug in station was built, the librarian randomly recorded 48 people speaking at the library. Their average decibel level was 66.5 and their standard deviation was 20. What can be concluded at the the α= 0.10 level of significance? a. The test statistic = (please show your answer to 3 decimal places.) b. The p-value = (Please show your answer to 4 decimal places.)

K A company is developing a new high performance wax for cross country ski racing. In order to justify the price marketing wants, the wax needs to be very fast. Specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion. To test it, the champion will ski the course 8 times. The champion's times (selected at random) are 54.9, 63.7, 48.1, 53.9, 49.3, 47.4, 53.7, and 44.9 seconds to complete the test course. Should they market the wax? Assume the assumptions and conditions for appropriate hypothesis testing are met for the sample. Use 0.05 as the P-value cutoff level. Choose the correct null and alternative hypotheses below. Ο A.

Data from the National Association of Realtors indicates that mean price of a home in Denver,Colorado, in the first three months of 2018 was $255,300. We can write this as 255.3 with unitsof thousands of dollars for our calculations. A random sample of 60 homes sold in 2020 had amean price of 235 (thousand dollars). Assume the standard deviation s = 140 (thousand dollars).Can we conclude that the mean price in 2020 differs from the mean price in the first 3 months of2018?

10. (S-AQ 11.45) To estimate the mean height µ of male students on your campus, you will measure an SRS of students. You know from government data that the standard deviation of the heights of young men is about 2.8 inches. You want your sample mean x to estimate p with an error of no more than one-half inch in either direction. What standard deviation (+0.0001) must x have so that 99.7% of all samples give an x within one-half inch of p? (Use the 68-95-99.7 rule)| How large an SRS do you need to reduce the standard deviation of x to the value you found in the previous part? eBook Hint Check Syntax
