The Third T-Test
Let's review the plots for the 'Purchase'
column of the control and test groups.
Levene's Test:
Now perform a t-test for the 'Purchase'
columns:
H₀: The mean values of the column do not differ between the groups.
Hₐ: The mean values of the column differ between the groups.
In this case, the p-value (0.350
) is higher than the acceptable significance level (0.05
), indicating that there is insufficient evidence to suggest that the mean values differ between the groups. Now it's your turn!
