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:
a = 4, b = - 5, c = 5
Step-by-step explanation:
Expand the product of factors on the left side and compare like terms on both sides.
(3x - 1)(ax + b) ← expand using FOIL
= 3ax² + 3bx - ax - b
= 3ax² + (3b - a)x - b
Equating coefficients of like terms with 12x² - 19x + c , then
3a = 12 ( divide both sides by 3 )
a = 4
3b - a = - 19
3b - 4 = - 19 ( add 4 to both sides )
3b = - 15 ( divide both sides by 3 )
b = - 5
c = - b = - ( - 5) = 5
For the first rectangle, you take 7ft x 4ft x 5ft which is equals to 140 ft^3.
For the second rectangle, you take 10 ft x 8ft x 6ft which equals to 480ft^3.
Answer:
5 days and 5 hours
Step-by-step explanation:
24*5=120
125-120=5
We suppose we have a regular polygon with n sides, then the measure of each one of the interior angles is given by:
For example, if we want to know the measure of a regular pentagon (which has 5 sides), we replace the value of n by 5,
And we obtain that each one of the interior angles of the pentagon is 108°.
