Use the graph of f to estimate the local maximum and local minimum. (5 points)
2 answers:
Answer:
Local maximum: (0,1)
Local minimum:
Step-by-step explanation:
To estimate the local maximum and local minimum using graph.
Local maximum: It is largest value of function for all other values of function near by.
Local minimum: It is smallest value of function for all other values of function near by.
A function has two extrema maxima or minima.
Please see the attachment for graph.
In graph highest point only 1, Only one local maximum at x=0
Local maximum: (0,1)
In graph two lowest point at
Local minimum:
Hence, Local maximum: (0,1) ; Local minimum:

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.
