Answer:
Mean = 910.2
Standard deviation = 12.8
Step-by-step explanation:
82% over the age of 25 are high school graduates.
A survey randomly selected students of certain country included 1110 who were over the age of 25 and 871 of them were high school.
n = 1110
p = 82% = 0.82
q = 1 - 0. 82
q = 0.18
Mean = np
= 1110*0.82
= 910.2
Standard deviation = √npq
= √ 1110*0.82*0.18
=√163.836
= 12.8
