Answer:
Test statistic =1.30
Step-by-step explanation:
Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.
Men Women Difference
Sample size n 60 120
Proportion p_1, p_2 0.45 0.35 0.10
60 120 180
0.45 0.35 0.383333333
27 42 69
p = 0.3833
Std error for proportion difference = 
Test statistic = 
=
=1.30
Answer:
Value of z = 7
Value of y = 30
Step-by-step explanation:
We are given the following equations in the question:

We have to solve the given equation for y and z.
Equating the two equations we get,

Value of z = 7
Value of y = 30
Answer:
0.184
Step-by-step explanation:
As the statistician consultant, I would have to calculate the chance of having 2 ambulances on the freeway at this hours and relay the message to the dispatcher.
Probability of having the need for 2 ambulances.
We will have a poisson distribution:
Lambda = 1
P(x=2) = e^-2*1/2!
= 2.71828^-1/2
= 0.368/2
= 0.184
I would tell the dispatch rider that the possibility that 2 ambulances would be required is 0.184.
Thank you
