Part a) How do you explain the results you got for the 2000 pairs? (discuss the mean and standard deviation of each column consisting of 1000 random numbers between 0 and 9

Part b) How do you explain the results you got for the 2000 pairs with respect to the confidence interval? why was it so narrow? how does the confidence interval including "0" relate to its p-value?

column 1 mean = 4.43 std dev = 2.65

column 2 mean = 4.42 std dev = 2.64

Answer #1

As the standard deviation of both the columns are almost same, this implies that the spread of the columns is almost same.

In case we want the wider confidence interval the confidence level should be increase.

As confidence inteval contains 0 this implies that the mean of two columns are not significantly different.

Result is not Statistically significant.
