Illusion [34]

Answer: a) 84 and b ) 2084

Step-by-step explanation:

Given : Sample standard deviation : s= $22.82

(Population standard deviation is unknown ) , so we use t-test.

Critical value or the​ 95% confidence intervals :t_{n-1}*=2.0

Formula to find the sample size :

n=(\dfrac{t^*\cdot s}{E})^2

a) E = 5

n=(\dfrac{(2)\cdot 22.82}{5})^2

n=(9.128)^2=83.320384\approx84

i.e. Required sample size : n= 84

b)  E = 1

n=(\dfrac{(2)\cdot 22.82}{1})^2

n=(45.64)^2=2083.0096\approx2084

i.e. Required sample size : n= 2084
