Step-by-step explanation:
Base: 7 × 13 = 91
Rectangle Sides: 6.1 × 13 = 79.3 (x2 = 158.6)
Triangle Sides: 5 × 7 = 35 (÷2 ×2 = 35)

Answer:
The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
A recent survey showed that among 100 randomly selected college seniors, 20 plan to attend graduate school and 80 do not.
This means that 
68% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).

Ticket Sellers
----------------------------------------------------------
1 ticket seller = $10 x 50
1 ticket seller = $500
12 ticket sellers = $500 x 12
12 ticket sellers = $6000

Cleaning person
----------------------------------------------------------
1 cleaning person = $7.50 x 50
1 cleaning person = $ 375
25 cleaning person = $375 x 25
25 cleaning person = $9375

Ushers
----------------------------------------------------------
1 usher = $8.50 x 50
1 usher = $425
15 ushers = $425 x 15
15 ushers = $6375
----------------------------------------------------------
Total
----------------------------------------------------------
$6000 + $9375 + $6375 = $21750
----------------------------------------------------------
Answer: Total monthly salary per month = $21750
