For your final project you will be conducting a research study. For the first paragraph the following steps should be followed. 1. Describe the population, sample, and statistic for the study. 2. Write a statement of the claims in that were tested in the project. 3. Conduct an alternative hypothesis testing and null, make conclusions based on your results. Given data is below

Sample size: 25

Class width: 8

Mean: 38.52

Median:38

Standard deviation: 12.03

Q1: 27.5

Q2: 51

95% Confidence interval for average age of online college students:

Using T-Distribution

Critical Value: 1.96

Margin of error: 4.96

Lower bound: 33.56

Upper bound: 43.48

95% Confidence interval for Proportion of Male online college students:

Sample size:25

Number of males: 7

Male proportion: 0.28 Female proportion: 0.72

Using Normal Distribution

Critical value: 1.96

Margin of error: 0.18

Lower bound: 0.10

Upper bound: 0.46

Using alpha=0.05 CL

Claim: The average age of online students is 32 years old
