Table 1: Two-Sample T-test For Private and Public Business Major regarding Cost
Private Public
Mean 211118.8 (u_1) 98685 (u_2)
P-value 0.000

Our null and alternative hypotheses are as below;
H_0: u_1- u_2=0
H_1: u_1- u_2≠0
From table 1, in the two-sample t-test analysis, we have a p-value of 0.000 which is less than 0.1, we will, therefore, reject the null hypothesis and conclude that there is sufficient evidence to show that the mean difference in the cost between private and public schools are different.
