A + C
(-5, -7) is 7 units to the left of point H
(-7, 7) is more than 7 units up and left of point H
the x axis is at (infinity, 0), being only 7 points up from point H
Solution :
Here, given :
Sample size, n = 39
Sample mean,
= 3.6
Standard deviation of the sample, s =2
The population mean, 
The significance level, 
a). Therefore the hypothesis is :

b). The test statics is given as :


= 1.873
c). The p- value is given by :



d). The conclusion :
In this case, the p-value is 
So, we do not reject
.
Therefore, we conclude that it is not a statistically significant difference between national average time for selling a home and the mean time for selling in Greene County.
