A random sample of 10 secretaries was asked to type a certain memorandum using both computers and typewriters, and the time required to finish the task was recorded for each secretary. A test of hypothesis will be conducted to determine if there is enough evidence to conclude that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance. If the computed statistic is 1.5, what is the correct decision and appropriate conclusion at 5% level of significance. I need help in this question a)Reject Ho. There is sufficient evidence that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance. b)Do not reject Ho. There is no sufficient evidence that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance.

Question
A random sample of 10 secretaries was asked to type a certain memorandum using both computers and typewriters, and the time required to finish the task was recorded for each secretary. A test of hypothesis will be conducted to determine if there is enough evidence to conclude that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance.
If the computed statistic is 1.5, what is the correct decision and appropriate conclusion at 5% level of significance.
I need help in this question
a)Reject Ho. There is sufficient evidence that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance.
b)Do not reject Ho. There is no sufficient evidence that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance.
c)Do not reject Ho. There is sufficient evidence that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance.
d)Reject Ho. There is no sufficient evidence that the average time required to type a memorandum is faster if female secretaries use computers rather than typewriters using a 5% significance level.
I know the options D and A are wrong but I can't seem to figure out the correct answer. I need help in solving and figuring out the correct option.
