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 :-
Using standard distribution table for z , we have
P-value=
Hence, the probability that at least 26 in the sample are unemployed =0.2643
