Answer:
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.
Prob student quits and receives $8000, thus costing the company $7950,
<span>is 0.003. </span>
<span>prob student doesn't quit, thereby contributing $50 to company income, </span>
<span>is 0.997 </span>
<span>Therefore expected receipt for company </span>
<span>= $(0.003*(-7950) + 0.997*50) </span>
<span>= $(49.85 - 23.85) </span>
<span>= $26
