Based on the t-test assuming equal variances on the T-TestEqual worksheet, is the difference in mean Total Price between the two sets of diamonds statistically significant? Yes, the absolute value of the calculated \( t \) Stat value is greater than the critical \( t \) value. Yes, the means appear to be similar. - No, the absolute value of the calculated \( t \) Stat value is less than the critical t value. No, the ratio of the variances is not greater than \( 4: 1 \).
