Researchers wanted to explore self-esteem in adolescent boys and adolescent girls. each respondent completed a 10-item self-esteem scale (they chose one rating for each item from a likert-type scale, 1 = strongly disagree and 5 = strongly agree). the sum of the 10 ratings was each respondent's self-esteem score. their results were: t = 2.01, d = .90 (40 girls, 40 boys).what statistical test did the researchers use to determine if there was a statisticallysignifcant di±erence in levels of self-esteem between the boys and the girls?

The statistical tests that researchers use to determine if there was a statisticallysignificant difference in levels of self-esteem between the boys and the girls were the T-test and Cohen's d.

Step-by-step explanation:

A statistical test is utilized to evaluate differences between groups (in this case, between boy and girls). The dependent variable was the self-esteem while the independent variable was the sex. A T-test is utilized to establish differences in the mean of two groups. The null hypothesis for a T-test is that means of the groups are the same; the statistical value is t. A Cohen's d test indicates standardized differences between the mean of both groups. It usually accompanies a T-test result; the statistical value is d.

D.  p ≤ 85 or p ≥ 125

You only have to meet 1 requirement, which A & B have 2.  

Due to the wording, at least 20 points, I would take that as meaning 105-20=85 is allowed or 105+20=125 is allowed.  

C, does not allow you to use 85,125.
