A 95% confidence interval for the difference in the population means is (11.97, 18.03). what is the interpretation of this interval?
a. the maintenance crew can be 95% confident that the interval from 11.97 to 18.03 captures the true difference in the mean temperatures (hot tub – pool).
b. the maintenance crew can be 95% confident that the interval from 11.97 to 18.03 captures the proportion of hot tub temperatures and the proportion of pool temperatures (hot tub – pool).
c. the maintenance crew can be 95% confident that the interval from 11.97 to 18.03 captures the true difference in the proportion of temperatures for all possible readings (hot tub – pool).
d.the maintenance crew can be 95% confident that the interval from 11.97 to 18.03 captures the difference in the sample mean hot tub temperatures and the sample mean pool temperatures (hot tub – pool).
