1. Consider the following data set:

D= (5, 10, 15, 15, 5, 10, 15, 15, 5, 10, 15, 15)

SD= 4.33

How would you add a number to this set while keeping the SD the same?

2. tossing a coin 50 times

A. from the 50 flips compute the proportion of heads from your 50 flips.

B. For a 95% confidence level find the z critical value

C. compute the 95% confidence interval for p, the margin of error from the 50 flips

D. compute the lower limit and upper limit of the 95% confidence interval
