$25.27 were spent on a pass and lunch for each student.
Step-by-step explanation:
Total students = 40
Teachers = 4
Amount spent on passes for students and teachers = $696.96
Amount spent on one pass = 
Amount spent on one pass = 
Amount spent on one pass = 
Amount spent of students' lunches = $377.20
Amount spent on one lunch = 
Amount spent on one lunch = 
Total spent on each student = Amount of one pass + amount of one lunch

$25.27 were spent on a pass and lunch for each student.

Answer:
a) 0.16
b) 0.0518
c) 
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
For a proportion p in a sample of size n, we have that the mean is
and the standard deviation is 
In this problem, we have that:

a. Find the mean of p, where p is the proportion of minority member applications in a random sample of 2100 that is drawn from all applications.
The mean of p is 0.16.
b. Find the standard deviation of p.

c. Compute an approximation for P ( p leq 0.15), which is the probability that there will be 15% or fewer minority member applications in a random sample of 2100 drawn from all applications. Round your answer to four decimal places.
This is the pvalue of Z when X = 0.15. So



has a pvalue of 0.4247
