Question

upper bound of the 95% confidence interval. Now do the hypothesis testing using the p-value and the alpha level comparison Independent Samples Test Levene's Test for Equality of Variances t-test for Equality of Means 95% Confidence Interval of the Difference Sig. (2- tailed) Mean Difference Std. Error Difference Sig Lower 2.28404 2.22234 df Upper n_of visits Equal variances 1.385 262 3.837 12 002 5.28571 1.37766 8.28739 assumed Equal variances not assumed 3.837 10.153 003 5.28571 1.37766 8.34909

Explanation / Answer

As Levene's test has p value=0.262 greater than alpha=0.05, hence accept the null hypothesis and conclude that Equal variance is assumed.

then we will look for corresponding p value It is 0.002 <alpha=0.05 Hence we will reject the null hypothesis of equality. And conclude that both samples have different mean.
