A grocery supplier believes that the mean number of broken eggs per dozen is 0.8 with a standard deviation of 0.6. You buy 8 doz
Aleks04 [339]

Answer:

Step-by-step explanation:

Given that a grocery supplier believes that the mean number of broken eggs per dozen is 0.8 with a standard deviation of 0.6.

Here we assume the cartons of eggs are independent

a) Mean value of eggs in 8 dozens = 8 Expected value in 1 dozen

= 8(0,8) = 6.4

b) Var (8x) (Here 8 dozens)

= 64 var(x)  (assuming independent)

Otherwise we have Var(x1+x2+x3+...)=sum of var of xis + cov (xi,xj)

Thus we have to assume independent to avoid covariance

So Var(8x)=64 Var(x)

STd dev for 8 dozens = 8(0,6) = 4.8

c) To avoid covariance i.e. variance among pairs of dozens we assume independence.
