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

(please show your answer to 3 decimal places.) O (Please show your answer to 4 decimal places.) O The results are statistically insignificant at a = 0.01, so there is statistically significant 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. O The results are statistically significant at a = 0.01, 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 a = 0.01, so there is sufficient evidence to conclude that the mean final exam score for the eleven men that were observed is more than the mean final exam score for the ten women that were observed. O The results are statistically insignificant at a = 0.01, 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.

(please show your answer to 3 decimal places.)
O
(Please show your answer to 4 decimal places.)
The results are statistically insignificant at a = 0.01, so there is statistically significant 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.
The results are statistically significant at a = 0.01, 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.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude
that the mean final exam score for the eleven men that were observed is more than the mean
final exam score for the ten women that were observed.
O The results are statistically insignificant at a = 0.01, 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.
