Question

ased on the tables below, answer the following questions (a) What is the mean number of children living at home among males? What is the mean number among females? (b) Is Levene's test significant? Should you use the top or bottom line to interpret the t test? (c) Is the ttest statistically significant? What do you conclude about these variables?

Explanation / Answer

a) The mean number of children living at home among males = 1.65 unit (though unit is not mentioned in the question)

The mean number of children living at home among females = 1.96 unit

b) P-value for Levene's test = 0.23 > 0.05, so at 5% level of significance we can conclude that Levene's test is not significant and variances are not significantly different.

So, one should use top line (i.e. equal variance assumed) to interpret the t test.

c) For t test, we get P-value = 0 < 0.05, so at at 5% level of significance we can conclude t test is significant and the mean number of children living at home among males and females are significantly different.
