18-30	31-50	50+
4	1	5
3	0	6
5	0	6
4	1	4
		5

Step 1: State the H_o and the H₁.(1 point)

H_{0 =}

H_{1 =}

Step 2: Identify the distribution and compute the df.(1 point)

distribution =

df =

Step 3: Identify the critical value of the test statistic and state the decision rule.(2 points)

= .05

critical value =

decision rule =
