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: 62°
Solution:
tan x =34/18
x=tan^-1 (34/18)
x=62°
Step-by-step explanation:
Representing inequalities on number line:
First of all we write the inequalities that are to be represented.
Let x represent the elevation of the miner at any time of the day.
The minimum elevation is 6 ft below the sea level. If we consider the sea level as 0 on the number line, the lower limit is -6.
The maximum elevation is 6 ft above the sea level. Hence the upper limit is 6.
The elevation throughout the day is represented by the inequality:
-6 ≤ x ≤ 6 and represented on the line as shown in the picture attached.
Note: The solid end points of the line at 6 and -6 means that 6 and -6 are included in the inequalities.
