No. of students to complete college = (30/100) x 100 = 30 Students
President wants to increase by 50% = (50/100) x 30 = 15 Students

Step-by-step explanation:
Test if the mean transaction time exceeds 60 seconds.
At the null hypothesis, we test if the mean transaction time is of 60 seconds, that is:
At the alternate hypothesis, we test if it exceeds, that is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
60 is tested at the null hypothesis:
This means that 
A sample of 16 ATM transactions shows a mean transaction time of 67 seconds with a standard deviation of 12 seconds.
This means that 
Value of the test statistic:
Thus, the correct answer is given by option b.
How many 50 miles are in 600 miles :
600 miles / 50 miles = 12
There are 12 slices of 50 miles in 600 miles.
1 slice of 50 miles equals 0.5 inch
(1 slice × 0.5 inch = 0.5 inch)
so
12 slices of 50 miles equals 6 inches
(12 slices × 0.5 inch = 6 inches)
The lenght of the freeway on the map is 6 inches.
