Suppose that, based on a sample, the 99.7% confidence interval for the mean of a population is (59,95). what is the mean of the sample?

mean = 77

Step-by-step explanation:

We have a confidence interval of (59, 95) with a confidence of  99.7 percent

99.7 is 6 standard deviations from the mean, 3 on each side of the mean

mean - 3 sigma = 59

mean + 3 sigma = 95

We can use elimination to eliminate sigma.  Add these equations together

mean - 3 sigma = 59

mean + 3 sigma = 95

2 * mean = 154

Divide each side by 2

2 * mean/2 = 154/2

mean = 77

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
