Answer:
There is no enough evidence to claim that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.
Step-by-step explanation:
The question is incomplete: the table is attached as picture.
The researcher was attempting to show statistically that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.
As result from the test we have a t-statistic with a value t=-1.37631.
We don't know the significance level, but we know that the critical value that separates the acceptance region from the rejection region is tc=-1.70113.
To be the difference between means statistically lower than 0, the t-statistic should be lower than the critical value.
This is not the case, so the null hypothesis failed to be rejected.
There is no enough evidence to claim that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.

Answer:
Step-by-step explanation:
2y = -3x - 4
y = -3/2x - 2
perp.:2/3
y - 0 = 2/3(x + 6)
y = 2/3x + 4
If a triangle has 180 degrees total with a right and of 90 and another of 45, then you would have 'B' with 45
Answer:
D. 1720 mm^2.
Step-by-step explanation:
This consists of 5 surfaces.
Area of 2 triangles + area of base + area of the side + area of the sloping side.
= 2 * 1/2 * 8 * 15 + 40*17 + 8*40 + 15*40
= 120 + 680 + 320 + 600
= 1720.
