Question

One instructor claims that less than 42% of all college algebra students have met the prerequisites for the class upon enrollment. To test this claim, she examined a random sample of 40 college algebra students' records, and found that of these, 11 have met the prerequisites. Use a level of significance of 10%.

What type of test will be used in this problem?
What evidence justifies the use of this test? Check all that apply
- The population standard deviation is not known
- The sample size is larger than 30
- The sample standard deviation is not known
- There are two different samples being compared
- The population standard deviation is known
- The original population is approximately normal
- np>10np>10 and n(1−p)>10n(1-p)>10
Enter the null hypothesis for this test.
H0H0
Enter the alternative hypothesis for this test.
H1:H1:
For this analysis, is the original claim located in the null or alternative hypothesis?
What is the test statistic for this test?
What is the p-value for this test?
What is the decision based on the given statistics?
What is the correct interpretation of this decision?

Using a % level of significance, there sufficient evidence to the claim that less than 42% of all college algebra students have met the prerequisites for the class upon enrollment.
