The mean age of a random sample of 35 people who were playing the slot machines is 48.7 years with a sample standard deviation of 6.8 years. The mean age of a random sample of 45 people who are playing roulette is 55.3 with a sample standard deviation of 3.2 years. Can it be concluded at a = .05 that the mean age of those playing slots is less than those playing roulette (is us < μr)? Assume that the population variances are equal. Test the null hypothesis Ho: μs-μr 20

Does it take a different amount of time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 48 seeds that were exposed to rock music took an average of 28 days to germinate. The standard deviation was 13 days. The 47 seeds that were exposed to classical music took an average of 32 days to germinate. The standard deviation for these seeds was 10 days. What can be concluded at the a - 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer Select an answers Select an answerv (please enter a decimal) Hị: Select an answer Select an answer Select an answer v (Please enter a decimal) c.
