Explanation / Answer

Answer

Test statistic, t = 3.720

Explanation

Levene's test for equality of variances suggests that there is no significant difference between the two population variances, since the F-statistic (1.038) is insignificant with p-value (0.310) greater than 0.05. Hence we can use independent sample t test assuming equal variances and hence the test statistic, t = 3.720
