Astudy was conducted to determine if the salaries of elementary school teachers from two neighboring states were equal. a sample of 100 teachers from each state was randomly selected. the mean from the first state was $29,100 with a population standard deviation of $2300. the mean from the second state was $30,500 with a population standard deviation of $2100. test the claim that the salaries from both states are equal. use ΅ = 0.05. justify your decision with work. write a short parargraph about the results of the test and what you can conclude about the claim.

After calculating values from test statics we come to know that value of if null hypothesis is true then it will rejected

As critical values of z is ±1.96 after apply the test statics formula , we get the value of z that is - 4.50 As we consider the equation that

H₀ > z

Apply test statistic we fine the true value . So there is sufficient evidence to reject the claim.

Step-by-step explanation:

critical values z₀ = ±1.96; standardized test statistic z ≅ -4.50;

reject H₀

There is sufficient evidence to reject the claim.

step-by-step explanation:

because i said it is

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
