A professor was doing a study to see if students perform better when they are using book homework or online homework. To
test this, he had one of his classes complete book homework and the other class complete online homework. He then randomly
selected students from each class and recorded their grade in the class, which is given below. Test the claim that the mean grade
for students using online homework is less than the mean grade for students using book homework at the a=0.05 level of
significance.

If you increase the sample size to 50 from 30, will the standard error of the mean be smaller or larger? Explain your reasoning.
Homeruns In 1998, Mark McGwire hit 70 homeruns,to break the single season home run record of 61 home runs set by Roger Maris in 1961. McGwire later admit-ted to using performance enhancing steroids that sea-son. Even so, how did McGwire’s performance really compare to Maris’s? The league was very different in1998 than in 1961. The table below shows the mean andstandard deviations for the number of home runs scoredby all players with at least 502 plate appearances in theirrespective seasons. Use these to determine who’s homerun feat was more impressive.

A psychologist has designed an index to measure the social perspectives of elementary school children. The index is based on ratings of a child’s responses to questions about a set of photographs showing different social situations. The following are the indices measured on a random sample of 16 children attending elementary school in a particular district. 48, 75, 69, 58, 60, 68, 59, 66, 71, 52, 49, 60, 54, 55, 70, 57 For the data the mean index is 60.69 and the standard deviation is 8.26. Perform a statistical test to determine if the population mean index is greater than 50. a) Name of hypothesis test: b) H0: c) HA: d) Test Statistic: e) Rejection region: f) Decision in the context of the problem:
