Question

A sample of n=500 individuals is asked how many hours theytypically spend using a computer in a week. The mean response is"x-bar" =8.3 hours, and the standard deviation is s=7.2 hours. Findvalues for the interval "x-bar" ± 2s, and explain why theresult is evidence that the distribution of weekely hours spentusing the computer is not bell-shaped.

Explanation / Answer

given that ,                    n=500 and mean=8.3hours                        sd=7.2hours                                                the C-I : 8.3±7.2/500 are(8.62,7.97) because it is not an exponential distribution
