A football team owner believes that attendance at the home stadium increases when the team has a winning season. Herandomly selects 10 seasons when the team won more games than they lost and determines that the mean attendance is88,532 people and the standard deviation is 1341 people. Ten more seasons are randomly selected from years whenthe team lost more games than they won with a mean of 86,910 people and a standard deviation of 1521 people.Assume all conditions for conducting a significance test have been met and that the p-value is 0.011. Which of thefollowing conclusions should the owner make?(a) The mean attendance at the home stadium is greater when the team is having a winning season approximately1.1% of the time.(b) The p-value indicates that the mean attendance at the home stadium is greater when the team is having awinning season at the 1% level of significance. There is a significant difference in mean attendance when theteam is winning than when the team is losing.(c) At the 5% significance level, there is evidence that the mean attendance at the home stadium is greater whenthe team is having a winning season than when the team is having a losing season. We would expect to get atest statistic at least as extreme as the one observed 1.1% of the time if the null hypothesis is true.(d) At the 5% significance level, there is evidence that the mean attendance at the home stadium is greater whenthe team is having a winning season than when the team is having a losing season. We would expect to get atest statistic at least as extreme as that observed 98.9% of the time if the null hypothesis is true.

A football team owner believes that attendance at the home stadium increases when the team has a winning season. He randomly selects 10 seasons when the team won more games than they lost and determines that the mean attendance is 88,532 people and the standard deviation is 1341 people. Ten more seasons are randomly selected from years when the team lost more games than they won with a mean of 86,910 people and a standard deviation of 1521 people. Assume all conditions for conducting a significance test have been met and that the p-value is 0.011. Which of the following conclusions should the owner make?

A researcher gathered data on five randomly selected individuals from a data set. The ages are 25, 27, 20, 21, and 29. What is the standard deviation for respondent's age?
A professor believes that, for the introductory art history classes at his university, the mean test score of students in the evening classes is lower than the mean test score of students in the morning classes. He collects data from a random sample of 250 students in evening classes and finds that they have a mean test score of 76.8. He knows the population standard deviation for the evening classes to be 7.2 points. A random sample of 200 students from morning classes results in a mean test score of 77.8. He knows the population standard deviation for the morning classes to be 1.9 points. Test his claim with a 90% level of confidence. Let students in the evening classes be Population 1 and let students in the morning classes be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
A Statistics instructor wanted to compare the scores on the same final exam given to students at a local community college and local university. The Statistics instructor feels that students at the community college would be better prepared and have higher exam scores on the final exam. After grading the final exams from both institutions, the Statistics instructor found that for a sample of 36 community college students, the sample had a mean score of 84 with a standard deviation of 3.4. A sample of 45 university students had a mean score 79 with a standard deviation of 2.6. Construct a 95% confidence interval for the difference between population mean exam scores. Round your final results to one decimal place. _____________ ≤ ??? − ????? ≤ ______________
You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation of 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. For the neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8. The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. What is the mean square within samples?

Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 37 randomly selected people who train in groups, and finds that they run a mean of 47.7 miles per week. Assume that the population standard deviation for group runners is known to be 3.3 miles per week. She also interviews a random sample of 49 people who train on their own and finds that they run a mean of 49.4 miles per week. Assume that the population standard deviation for people who run by themselves is 4.4 miles per week. Test the claim at the 0.10 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2. Step 2 of 3 : Compute the value of the test statistic.
