A study on women’s weights was recently completed.
Twenty randomly selected high school females from an urban setting were compared to $21$ randomly selected females from a rural setting. The results are below:
Two-Sample T for Urban Weights vs. Rural Weights
Difference = $\mu$ (Urban Weights) - $\mu$ (Rural Weights)
Estimate for difference: $-2.68$
$95\%$ CI for difference: ($-10.22, 4.824$)
T-test of difference = $0$ (vs. not =): T-value = $-0.73$ P-value = $0.472$ DF = $37.8$
Describe the sampling distribution of the difference between urban and rural weights.
