Test the claim that the mean GPA of night students is significantly different than the mean GPA of day students at the 0.02 significance level. The null and alternative hypothesis would be: Ho:µN = µD Họ:µn= µD Ho:µN = µD HA:HN + HD HẠ:µN < µd_HA:µN > µD The test is: left-tailed right-tailed two-tailed The sample consisted of 30 night students, with a sample mean GPA of 2.68 and a standard deviation of 0.3, and 40 day students, with a sample mean GPA of 2.61 and a standard deviation of 0.2. The test statistic is: |(to 2 decimals) The p-value is: (to 2 decimals)
