The International League of Triple-A minor league baseball consists of 14 teams organized into three divisions: North, South, and West. Suppose the following data show the average attendance for the 14 teams in the International League. Also shown are the teams' records; W denotes the number of games won, L denotes the number of games lost, and PCT is the proportion of games played that were won.

Question Help ▼ Summary statistics for the scores of the 27 students who completed a Dental Anxiety Scale questionnaire are x = 10.5 and s=3.3, Scores range from 0 (no anxiety) to 20 (extreme anxiety). Conduct a test of hypothesis to determine whether the mean Dental Anxiety Scale score for the population of college students differs from u= 11. Use a = 0.05. State the null and alternative hypotheses. Choose the correct answer below. A. Ho: H=11 versus H: u11 O B. Ho: H 11 versus H: u = 11 OC. Ho: H=11 versus Hn: H > 11 The test statistic for this small-sample test of a population mean is. (Round to two decimal places as needed.)
As a psychiatrist you developed a test to measure happiness. Test the claim that the mean measure of happiness for females is equal to the mean measure of happiness for males. Use a significance level of .10. The data is given below. (although you could label group 1 to be male or female and get the same answer at the end, the middle would vary a little. So to match with me call group 1 females) (3 decimals) females males 9.6 7.6 8.9 6.9 6.7 9.6 6.3 5.8 7.1 9.4 6.1 7.3 C: μ1=μ2 HA;μ1#μ2 Ho: [Select] [Select] 8.4 7.9 9.7 P=[Select] 8.8 [Select] 7.8 Pis [Select] The data [Select] Critical value/s is [Select] + =-1.849 + (although you are rounding to 3 decimals this one ends up with only 2) the claim. +

A psychologist wants to test whether there is any difference in puzzle-solving abilities between boys and girls. Independent samples of twelve boys and fourteen girls were chosen at random. The boys took a mean of 37 minutes to solve a certain puzzle, with a standard deviation of 4.3 minutes. The girls took a mean of 32 minutes to solve the same puzzle, with a standard deviation of 5.4 minutes. Assume that the two populations of completion times are normally distributed, and that the population variances are equal. Can we conclude, at the 0.05 level of significance, that the mean puzzle-solving times for boys, µ, differs from the mean puzzle-solving times for girls, µ,? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
