A statistics instructor, when asked how students do on the first statistics exams claims that the mean score for all students on the first exam is less than 75. To test this claim, 22 students are selected at random. Their scores from the first exam had a mean of 74.2 with a standard deviation of 13.95. Test the instructor’s claim at the 0.01 level of significance. Step 5: There __________ sufficient evidence to conclude that __________________

A study is conducted to compare the performance of students with more than one personal electronic gadget and those with only one. A number of them were taken as subjects for the study. The mean grades of these students and the standard deviations are shown below: For one gadget: The mean is 83, standard deviation is 12, and sample size is 7. For more than one gadget: The mean is 79, standard deviation is 13, and sample size is 5. Is it possible to conclude that there is no significant difference in the mean grades of the two types of students at a 95% confidence interval? Note: This is a two-tailed test. Also take note that this is finding the difference between two population means.
I. There are two samples with means 15 and 18. Both of those samples consist of 24 observations. Sample standard deviations are equal to 4 in both cases. If you want to test whether the difference between the mean in the first and the mean in the second population is equal to 0, what is your decision at the .01 level?

Last year, the average amount that teams for the Statistics Games raised was $375. Have teams been more successful at fundraising this year? To find out, you take a random sample of 36 teams. Your sample of 36 teams yields a mean of $396 and a standard deviation of $70. Might you have made a Type 1 or Type 2 error? A Type 1. This means that we said that the mean amount raised had increased, when it was actually still $375. B You might have made a calculation error. C Neither- we're sure the average has increased. D Type 2. This would mean that we said there was not enough evidence to say the mean had increased from $375, when it actually is higher than $375. E Either kind is possible!

Which one of the following statements is false? The median rating for Aggressiveness is higher for the Tearless image than for the Tearful image. The standard deviations for both groups are similar. At least one quarter of the respondents in each group rated the dog’s aggressiveness as 0. The distribution of Aggressiveness is positively (right) skewed for both the Tearful and the Tearless image. No one who saw the Tearful dog rated its aggressiveness as 8 or 9.
