Expert Answer
Margin of error:
The formula of margin of error for confidence interval is as follows:

Upper bound- Lower bound E = 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:

72-68 E = 2 2 =2
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...
