Answer:
   M(h) = 73.18025h
Step-by-step explanation:
The composite function is ...
   M(B(L(h))) = M(B(28.75h)) = M(1.78(28.75h)) = M(51.175h)
   = 1.43(51.175h) = 73.18025h
The composite function is ...
   M(h) = M(B(L(h))) = 73.18025h

Answer: 0.2643
Step-by-step explanation:
Given : The proportion of  adults are unemployed : p=0.077
The sample size = 300
By suing normal approximation to the binomial , we have


Now, using formula  , the z-value corresponding to 26 will be :-
, the z-value corresponding to 26 will be :-
 
Using standard distribution table for z , we have
P-value=

Hence, the probability that at least 26 in the sample are unemployed  =0.2643
