Step 2

a) Computation of margin of error for the confidence interval (68<µ<72):

The confidence interval for the mean is given as 68<µ<72.

Here, the upper bound is 72 and the lower bound is 68.

The margin of error for the confidence interval (68<µ<72) is obtained as 2, from the calculation given below:

Step 3

b) Computation of margin of error for the confidence interval (0.623<p<0.626):

The confidence interval for the proportion is given as 0.623<p<0.626.

Here, the upper bound is 0.626 and the lower bou...
