Use the acupuncture data set https://1drv.ms/x/s!ApAjhIcc8n1EgXAhDzbH17BlDtZx?e=97Cdnn Read the introduction and the data dictionary before beginning. For this you will construct confidence intervals for treatment and control groups to make inferences about the difference between the groups

1. Instructions: Fill in the following tables: 1. Treatment group by gender

	Treatment	Control	Overall
Total subject in each group
Total number of females in each group
Proportion of females in each group
95% CI for the proportion of females in each group

2. Treatment Group and age

	Treatment	Control	Overall
Total subject in each group
Mean age for each group
Standard Deviation for each group
95% CI for the mean age of each group

a. Based on the confidence intervals from part a, would you conclude that the proportion of females differs between the treatment and control groups? Justify your answer.

b. Based on the confidence intervals from part b, would you conclude that the mean age differs between the treatment and control groups? Justify your answer.

c. Since the data is from a randomized control trial, should the proportion of females and mean age differ between the treatment and control groups?Justify your answer.

2. Fill in the following tables:

	Treatment	Control
95% CI for mean headache frequency after 1 year (f5)
95% CI for mean headache severity score after 1 year (pk5)

Based on your confidence intervals, does it appear that acupuncture is effective in treating headaches? Justify your answer. Data set: https://1drv.ms/x/s!ApAjhIcc8n1EgXAhDzbH17BlDtZx?e=97Cdnn
