Using the following

−1.0173 −0.3243 0.36416 0.96709 −0.7724 −0.1004 0.49382 0.98607 −0.7492 −0.0661 0.49734 1.08517 −0.6438 0.08449 0.51945 1.15909 −0.5727 0.11064 0.64080 1.23061 −0.4562 0.15022 0.66312 1.30328 −0.3986 0.25865 0.84739 1.57912

Sum 7.83952 Count 28 Sum of squares 16.1280

Determine a confidence interval for the mean of the normal distribution we sampled above, for at least one confidence level of your choice.

Expert Solution

Mean = Sum/Count = 7.83952/28

Mean = 0.28

SD = sqrt((16.1280-7.83952^2/28)/(28-1))

SD = 0.71836

95% Confidence Interval Calculation

A 95% confidence interval for the mean of the normal distribution is (0.001,0.559).

90% Confidence Interval Calculation

A 90% confidence interval for the mean of the normal distribution is (0.049,0.511).
