Question
Test the claim that the mean GPA of night students is smaller than 2.5 at the 10% significance level. The population standard deviation for this group is known to be 0.16.

The null and alternative hypotheses for this test are:

\(H_0: \mu \leq 2.5 \)  
\(H_A: \mu > 2.5 \)  

\(H_0: \mu \geq 2.5 \)  
\(H_A: \mu < 2.5 \)  

The test is:  
- left-tailed 
- right-tailed 

Based on a sample of 30 people, the sample mean GPA was 2.47.  
*Hint: Before you find the p-value below, calculate the test statistic to two decimal places.*

The p-value is: ___________ (to 4 decimals)  

The significance level as a decimal is: ___________

Based on this, 
- fail to reject the null hypothesis, \(H_0\)
- reject the null hypothesis, \(H_0\)
