A random sample of n measurements was selected from a population with unknown mean

and standard deviation= 35 for each of the situations in parts a through d. Calculate a

95% confidence interval for for each of these situations.

a.N = 60, x = 24

b.N = 200, x = 102

c.n = 125, x = 17

d.N = 125, x = 5.29

(Round to two decimal places)
