Answer:
The statistic for this case would be:

And replacing we got:

Step-by-step explanation:
For this case we have the following info:
represent the sample size
represent the number of employees that earn more than 50000

We want to test the following hypothesis:
Nul hyp. 
Alternative hyp : 
The statistic for this case would be:

And replacing we got:

And the p value would be given by:

Answer:
0.705
Step-by-step explanation:
Data:
walks=0.65 and is late=0.4;is not late=0.6
cycles=0.35 and is late=0.1;is not late=0.9
The probability of sheila walking and not being late:
0.65 x 0.6=0.39
AND probability of being not late and cycling:
0.35 x 0.9=0.315
therefore,the probability of sheila walking or cycling and still not being late:
0.39+0.315=0.705
13, 15, 23, 24, 25
Median is 23 because it comes in middle of five numbers
To find the mean, add up the values in the data set and then divide by the number of values that you added
if we sum these numbers we get 100 then divide it by 5 we get
100/5 = 20
Answer:

Step-by-step explanation:

Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:

To get the answer i used a graph
then i tried just evaluating the equation
Reduce the expression, if possible, by cancelling the common factors.

I got the same answer so i believe this should be your Answer
<u>Hope this helps</u>
