The lengths of steel rods produced by a shearing process are normally distributed. Arandom sample of 10 rods is selected; the sample mean length is 119.05 centimetres, and the sample standard deviation is 0.10 centimetres. The 95% confidence interval for the population mean rod length is O 118.85 to 119.25 O 118.98 to 119.12 O 118.82 to 119.28 O 119.89 to 122.12 O 118.99 to 119.11

from a random sample of 35 months from January 2006 through December 2020, the mean number of tornadoes per in the united states was about 100. Assume the population standard deviation is 111. Construct a 90% and 95% confidence interval for the population mean.
The average number of pages per book from a library is unknown. A random sample of books from the library yields a sample mean of x¯=149.7 pages. Assume the sampling distribution of the mean has a standard deviation of σx¯=14.1 pages. Use the Empirical Rule to construct a 99.7% confidence interval for the true population mean number of pages.

According to an article in Good Housekeeping, a 128-lb woman who walks for 30 minutes four times a week at a steady, four-mi/hr pace can lose up to 10 lbs over a span of a year. Suppose 35 women with weights between 125 and 130lb perform the four walks per week for a year and at the end of the year the average weight loss for the 35 was 9.1 lbs. If the sample standard deviation is 5, calculate the value of the test statistic and find the p-value of the hypothesis test of Ho:µ =10 vs H1:µ≠10.
