A. The data in worksheet 2 of the Excel file represents the weights of 50 students before the Covid-19 pandemic began and their weight six months afterwards. You would like to determine whether there has been a significant increase in students' average weights over the six month period.

Analyze the data at the 0.05 level of significance (alpha) and provide the observed test statistic. Round final answers to two decimal places and include a negative sign if appropriate (e.g.,- 1.11). A positive sign does not need to be included.

B. he data in worksheet 2 of the Excel file represents the weights of 50 students before the Covid-19 pandemic began and their weight six months afterwards. You would like to determine whether there has been a significant increase in students' average weights over the six month period.

Indicate the correct hypothesis for this test

Select one: a. Ho: Ud > 0 ; H1: Ud U2 c. Ho: Ud =0; H1: Ud ? 0 d. Ho: Ud 0 e. Ho: U1 =U2 ; H1: U1 ? U2 f. Ho: U1 > U2 ; H1: U1

Analyze the data at the 0.05 level of significance (alpha) and provide the correct p-value Round final answers to two decimal places (e.g., 0.00).

C.The data in worksheet 2 of the Excel file represents the weights of 50 students before the Covid-19 pandemic began and their weight six months afterwards. You would like to determine whether there has been a significant increase in students' average weights over the six month period. The level of significance is 0.05 Provide the statistical decision of the test. Select one: a. Fail to reject the alternative hypothesis b. Reject the null hypothesis c. Reject the alternative hypothesis d. Fail to reject the null hypothesis
