1.Jaywalking is a huge safety issue inOxford, often causing cars to get into accidents. Use the data below to establish hypotheses and calculate the ANOVA for the relationship between age and number of citations for jay walking.State and explain your decision with regard to whether the H₀is ultimately rejected or retained.

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

Step 1: State the H_oand the H₁.

H₀:

H₁:

Step 2: Identify the distribution and compute the df.

The distribution is_______distribution.

df_B

df_W=

Step 3: Identify the critical value of the test statistic and state the decision rule.

=

critical value =

Step 4:Reviewthe obtained value of the test statistic.

Grand Mean:

Total Sums of Squares:

Between-groups Sums of Squares:

= 4(4 - 3.38)²+ 4(0.5 - 3.38)²+ 5(5.2 - 3.38)²

= 4(0.62)²+ 4(-2.88)²+ 5(1.82)²

4(0.3844)(8.2944)(3.3124)

1.54 + 33.18 + 16.56 = 51.28

Within-groups Sums of Squares:

SS_WSS_T-SS_B57.08 - 51.28 = 5.8

Compute theMean Squares:

MS_W=

Compute theFstatistic:

Step 5: Make a decision about the null and state the substantive conclusion.
