a. Whether these results indicate a significant change in the accident rate using binomial test, following the change in school start time using a two-tailed test with α = 0.05 . b. Because the outcome of the binomial test is a borderline z -score, use the real limits for X = 45 to determine if the entire z -score interval is located in the critical region. If any part of the interval is not in the critical region, the correct decision is to fail to reject the null hypothesis.

Question

Two measurements are made of some quantity. For the first measurement, the average is 74.4528, the RMS error is 6.7441, and the uncertainty of the mean is 0.9264. For the second one, the average is 76.8415, the standard deviation is 8.3348, and the uncertainty of the mean is 1.1448. The expected value is exactly 75. 13. Express the first measurement in public notation. 14. Is there a significant difference between the two measurements? 1 15. How does the first measurement compare with the expected value? 16. How does the second measurement compare with the expected value?

Question

Chapter 18, Problem 9P

To determine

a. Whether these results indicate a significant change in the accident rate using binomial test, following the change in school start time using a two-tailed test with α=0.05 .

b. Because the outcome of the binomial test is a borderline z-score, use the real limits for X = 45 to determine if the entire z-score interval is located in the critical region. If any part of the interval is not in the critical region, the correct decision is to fail to reject the null hypothesis.

A hat contains slips of paper numbered 1 through 6. You draw two slips of paper at random from the hat,without replacing the first slip into the hat.(a) (5 points) Write out the sample space S for this experiment.(b) (5 points) Express the event E : {the sum of the numbers on the slips of paper is 4} as a subset of S.(c) (5 points) Find P(E)(d) (5 points) Let F = {the larger minus the smaller number is 0}. What is P(F )?(e) (5 points) Are E and F disjoint? Why or why not?(f) (5 points) Find P(E ∪ F )

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
