A researcher utilizes a t-test to compare the average amount of beta-lactamase produced by two different types of bacteria. The Levene's test for equality of variances has a p value of 0.09. You know this means:
A) You should report the t-test results associated with assuming equal variances.
B) You should report the t-test results associated with NOT assuming equal variances.
C) The t-test is not significant so you should fail to reject the null hypothesis.
D) The t-test is statistically significant so you should reject the null hypothesis.

The p-value of 0.09 from Levene's test indicates that there is no significant difference in variances between the two groups (since it is greater than 0.05), so you should assume equal variances when reporting the t-test results.
