Where:
n = Required sample size
σ = Standard deviation = 18.3
E = Margin of error = 1/2 year
= Critical score from the confidence level = 1.645
Therefore,
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.
Answer:
x ≈ 0.290640965127
Step-by-step explanation:
