In: Statistics and Probability
Solution :
Given that,
=
x / n = 59.72 / 10 = 5.972
Sample size = n = 10
= 2.58
Z/2
= 1.96
Margin of error = E = Z/2*
(
/
n)
= 1.96 * (2.58 /
10)
= 1.57
At 95% confidence interval estimate of the population mean is,
- E <
<
+ E
5.972 - 1.57 <
< 5.972 + 1.57
4.402 <
< 7.542
(4.40, 7.54)
