Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The proportion that live with their parents is
The sample size is n = 125
Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution
i.e
Now the mean is evaluated as
Generally the proportion that are not staying with parents is
= >
The standard deviation is mathematically evaluated as
Given the n is large then we can use normal approximation to evaluate the probability as follows
Now applying continuity correction
Generally
So for the z - table
