10. Research found that students reported a Fall 2019 proportion of driving no more than 20 miles was 40%. Your sample of students indicated that 16 of 30 students drove no more than 20 mil per day. Research question: Is the reported Fall 2019 proportion significantly less than the Fall 2020 proportion? Be prepared to round final answers to hundredth place and to type Z or t table scores exactly as presented in the tables.

Expert Solution
Step 1

Given Information : 

Research found that students reported a Fall 2019 proportion of driving no more than 20 miles was 40% . Your sample of students indicated that 16 of 30 students drove no more than 20 miles per day .

Research question :  The reported Fall 2019 proportion significantly less than the Fall 2020 proportion  . 

The following information is provided: The sample size is , the number of favorable cases is , and the sample proportion is  p^, and the significance level is

Null and Alternative Hypotheses

The following null and alternative hypotheses need to be tested:

Ho: p = 0.40

Ha: p < 0.40

This corresponds to a left-tailed test, for which a z-test for one population proportion needs to be used.
