The mayor of a town has proposed a plan for the annexation of an adjoining community. A political study took a sample of 900 voters in the town and found that 37% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is more than 33%. Find the value of the test statistic. Round your answer to two decimal places

The value of the test statistic is 2.49              

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 900

p = 33% = 0.33

Sample proportion of the residents favored annexation = 37%

First, we design the null and the alternate hypothesis  

This is a one-tailed(right) test.  

Formula:

Putting the values, we get,

Thus, the value of the test statistic is 2.49

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
