Answer:
a) the probability that Company A will get the discount is 0
b) the probability that Company B will get the discount is 0.2753
c) the probability that Company C will get the discount is 0.9986
Step-by-step explanation:
a) Let p(m) be the <em>minimum</em> proportion of workers needed at Company A who use public transportation to get to work in order the company can get discount offer by the transit authority.
Then ≈ 0.1031
The probability that Company A will get the discount can be stated as
P(z>z*) (p-value of z*) where z* is the z-score of 0.103 in the distribution of proportion of workers in the city who use public transportation to get to work.
z* can be calculated using the equation
where
- p(m) is the minimum proportion needed for company A get discount (0.1031)
- p is the proportion of workers in the city who use public transportation to get to work (0.05)
- N is the number of employees of Company A (291)
Then z*= ≈ 4.15
P(z>4.15)=1-P(z<4.15)=1-1=0
b) for Company B:
≈ 0.0556
z*= ≈ 0.597
P(z>0.597)=1-P(z<0.597)= 1-0.7247=0.2753
c) for Company C:
≈ 0.0296
z*= ≈ -2.979
P(z>-2.979)=1-P(z<-2.979)=1-0.0014=0.9986
