Question

Do men score higher on average compared to women on their statistics finals? Final exam scores of thirteen randomly selected male statistics students and eleven randomly selected female statistics students are shown below. Male: 62 81 73 57 83 67 75 94 77 80 90 83 76 Female: 69 75 57 67 80 66 58 78 80 71 85 Assume both follow a Normal distribution. What can be concluded at the ? = 0.10 level of significance? For this study, we should use a. The null and alternative hypotheses would be: H0: ?m = ?f Ha: ?m > ?f b. The test statistic t = (please show your answer to 4 decimal places.) c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is ? e. Based on this, we should the null hypothesis. f. Thus, the final conclusion is that... The results are statistically insignificant at ? = 0.10, so there is insufficient evidence to conclude that the population mean statistics final exam score for men is more than the population mean statistics final exam score for women. The results are statistically significant at ? = 0.10, so there is sufficient evidence to conclude that the population mean statistics final exam score for men is more than the population mean statistics final exam score for women. The results are statistically significant at ? = 0.10, so there is sufficient evidence to conclude that the mean final exam score for the thirteen men that were observed is more than the mean final exam score for the eleven women that were observed. The results are statistically insignificant at ? = 0.10, so there is sufficient evidence to conclude that the population mean statistics final exam score for men is equal to the population mean statistics final exam score for women.

Do men score higher on average compared to women on their statistics finals? Final exam scores of thirteen randomly selected male statistics students and eleven randomly selected female statistics students are shown below.

Male: 62 81 73 57 83 67 75 94 77 80 90 83 76
Female: 69 75 57 67 80 66 58 78 80 71 85

Assume both follow a Normal distribution. What can be concluded at the ? = 0.10 level of significance?

For this study, we should use ________

a. The null and alternative hypotheses would be:

H0: ?m = ?f
Ha: ?m > ?f

b. The test statistic t = ______ (please show your answer to 4 decimal places.)

c. The p-value = ______ (Please show your answer to 4 decimal places.)

d. The p-value is ______ ?

e. Based on this, we should ______ the null hypothesis.

f. Thus, the final conclusion is that...

The results are statistically insignificant at ? = 0.10, so there is insufficient evidence to conclude that the population mean statistics final exam score for men is more than the population mean statistics final exam score for women.

The results are statistically significant at ? = 0.10, so there is sufficient evidence to conclude that the population mean statistics final exam score for men is more than the population mean statistics final exam score for women.

The results are statistically significant at ? = 0.10, so there is sufficient evidence to conclude that the mean final exam score for the thirteen men that were observed is more than the mean final exam score for the eleven women that were observed.

The results are statistically insignificant at ? = 0.10, so there is sufficient evidence to conclude that the population mean statistics final exam score for men is equal to the population mean statistics final exam score for women.
