Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 151 138 134 131 134 Left arm 173 166 188 154 136 In this example, up is the mean value of the differences d for the population of all pairs of data, where each individual ons difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test?

Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the mean of the population of differences between hospital admissions. Use the confidence interval to test the claim that when the 13th day of a month falls on a Friday, the numbers of hospital admissions from motor vehicle crashes are not affected. Friday the 6th Friday the 13th In this example, up is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the number of hospital admissions on Friday the 6th minus the number of hospital admissions on Friday the 13th. Find the 95% confidence interval.

Using a 0.05 significance level, test the claim that there is no difference between the yields from the two types of seed. Let jig be the mean of the population of differences of type 1 minus type 2 and write the hypotheses. The null hypothesis is Ho: Ha = 0. The alternative hypothesis is H10 Hq # 0.
