QUESTION 1 The president of this school claims that average GPA of students in this school is 3.0 with standard deviation 0.3. But, in our class, with 25 students, we find the class average is 2.9. We want to check weather we can reject the claim. For this purpose, we conduct a hypothesis testing. We set H0, the null hypothesis is HO: mu=3.0. The alternative hypothesis Ha is: mu>3.0 mu<3.0 mu=2.9 mu not equal 3.0 QUESTION 2 (continue 1). For this testing problem, find the value of the test statistic is: 1.66 -2.16 -1.67 1.21 QUESTION 3 (continue 2). The p-value is. 0.0475 0.0950 0.0154 0.1131

Transcribed Image Text:**Question 1**
The president of this school claims that the average GPA of students in this school is 3.0 with a standard deviation of 0.3. However, in our class, with 25 students, we find the class average is 2.9. We want to check whether we can reject the claim. For this purpose, we conduct hypothesis testing. We set H0, the null hypothesis as H0: μ = 3.0. The alternative hypothesis Ha is:
- ○ μ > 3.0
- ○ μ < 3.0
- ● μ = 2.9
- ○ μ ≠ 3.0
**Question 2**
(Continue 1). For this testing problem, find the value of the test statistic:
- ○ 1.66
- ● -2.16
- ○ -1.67
- ○ 1.21
**Question 3**
(Continue 2). The p-value is:
- ○ 0.0475
- ○ 0.0950
- ● 0.0154
