The mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.
Given,
number of workers chosen , n=12
percentage of respondents =62%
from given data the calculation are done according to binomial distribution,
then,
probability of respondents ,
a)calculating mean,

b)calculating standard deviation,

Thus, the mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.

Cookies baked = 12 × 3 (number of trays) = 36
Bags = 4
In 4 bags = 36 cookies
in 1 bag = 36/4 = 9 cookies (divide both sides by 4)
SO 9 COOKIES WERE PLACED IN EACH BAG
hope this helped :)
