The fire department in a large city is examining its promotion policy to assess if there is evidence of age discrimination. A random sample of 248 promotion decisions over the past 5 years gives the following information: 39 or younger 40 or older
Promoted 38 46
Not Promoted 80 84

This data will be used to test if there is a relationship between age and promotion decision.

Required:
a. If there were no relationship between age and whether or not a firefighter was promoted, how many firefighters age 40 or older would we expect to be promoted?
b. What is the value of the Chi-square statistic for this test?

A)

Hence the answer is 44.032.

B)

The value of -test statistic for this test 0.280.

Step-by-step explanation:

A) The number of fire-fighter of age 40 or older to be promoted ith observed value 46 is to be expected 44.032 as calculated above,

So the answer is 44.032.

B) The value of - test statistic is given by the formula,

The value of -test statistic for this test 0.280.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

black lol
