Sladkaya [172]

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 ,p=\frac{62}{100}=0.62

a)calculating mean,

\mu=n*p\\\\\mu=12*0.62\\\\\mu=7.44

b)calculating standard deviation,

\sigma=\sqrt{n*p*(1-p)}\\\\\sigma=\sqrt{12*0.62*(1-0.62)}\\\\\sigma=\sqrt{7.44(0.38)}\\\\\sigma=\sqrt{2.8272}\\\\\sigma=1.6814

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

in 1 bag = 36/4 = 9 cookies (divide both sides by 4)
SO 9 COOKIES WERE PLACED IN EACH BAG


hope this helped :)
