Basically trying to figure out once you get the test statistics how you determine critical value through the Table chart.
Trying to find critical value for test statistics of 2.36 with 10 subjects, 7 had higher scores, 2 had lower scores, and 1 score did not change. Using the traditional method of hypothesis testing. Use an alpha level of .01.
Trying to find the critical value of scores of girls are smarter than boys on tests. Assume the degrees of freedom for this problem is 27. The test statistic was 2.69 (alpha equals .05). If the mean of the boys score was lower than the mean of the girls score can she reject her null hypothesis?
Finding critical value, t score of randomly selected 217 students and found that they had education with a mean of 7.89 years and a standard deviation of 3.67 years. They also randomly selected 152 faculty and found that they had education with a mean of 5.99 years and a standard deviation of 3.65 years. Use a 0.01 significance level to test the claim that student cars are older than faculty cars.
To find the critical value of t and z.
