QUESTION 4: Illustrate the distribution of Gender and Class level by creating a graph QUESTION 6: Answer the following questions based on your results.
that includes both variables in a single Bar graph or Column graph
Do NOT include bars for the total row/column on the graph. A If a male student is randomly selected from the sample, what is the probability that it is a freshman ?
Answer A
B If we select a JUNIOR from the sample, what is the probability that is a FEMALE ?
Answer B
C If a student selected from the sample, what is the probability that the selected student is a male sophmore ?
Answer C
D What is the percentage of SENIORS in the sample ?
Answer D

AGE

Assuming this data represents a random sample of all US college students,
Use an appropriate statistical inference procedure from the ones we've studied so answer the questions below.
QUESTION 7 Based on this sample, is there evidence that male students are older on the average than female students ?
Use significance level alpha=1%. Is the conclusion the same using significance level alpha = 10% ? Comment on your results

LOANBALANCE

Assuming this data represents a random sample of all US college students,
Use an appropriate statistical inference procedure from the ones we've studied so answer the questions below based on this sample.
QUESTION 9a Provide a point estimate and a 95% confidence interval for the average loan balance of US college students with loans.
Assume that the population standard deviation for the loan balance of students with loans is known to be $1,850.
Include a copy of all work, including pivot tables and/ or templates used. HINT: CONSIDER ONLY STUDENTS WITH LOANS.
