Men Women Sample size 42 48 Sample Mean 438 506 Population standard Deviation 80 76 . At the 0.14 significance level, do women save more money than men? What is the value of the critical value for this hyporthesis test? 1.489 1.087 6.405 3.405

Solution

Here total degrees of freedom = (42-1)+(48-1)= 88

The t-value with 88 degrees of freedom at 0.14 level is 1.087

Answer is 1.087
