Final answer:
The population proportion of non-traditional students is calculated by dividing the number of non-traditional students (252) by the total student population (986). The mean of the sampling distribution is equal to the population proportion, and the standard deviation of the sampling distribution is found using the formula for proportions with a given sample size n.
Step-by-step explanation:
To find the population proportion of non-traditional students at the small community college with a student population of 986, out of which 252 are non-traditional, you would divide the number of non-traditional students by the total number of students. The proportion (P) is calculated as P = 252 / 986.
As for the mean (μ) and standard deviation (σ) of the sampling distribution of the proportion for samples of size n, they are calculated under the assumption that the population's distribution is approximately normal and that the sample size (n) is sufficiently large, meaning np ≥ 10 and nq ≥ 10 where q = 1 - p.
The mean of the sampling distribution is the same as the population proportion, so μ = P. The standard deviation for the sampling distribution is calculated using the formula σ = √{(P(1 - P)/n)}.
Notice that the actual sample size (n) hasn't been provided, so you will need to substitute the specific value of n whenever you have it to find the standard deviation for a given sample size.
