Question

Suppose you are testing if speeding tickets are given out in equal proportions on each day of the week. You were testing at the alpha is 0.05 level of significance. You get a P-value of 0.03. What can you conclude (your answer should include the words speeding tickets)?

Answer 1

Solution:

Given:

We are testing  if speeding tickets are given out in equal proportions on each day of the week.

Thus hypothesis of the study are:

H0: speeding tickets are given out in equal proportions on each day of the week

Vs

H1: speeding tickets are given out in different proportions on each day of the week.

Level of significance = 0.05

P-value = 0.03

Decision Rule: Reject H0, if P-value < level of significance, otherwise we fail to reject H0.

Since P-value = 0.03 < 0.05 level of significance, we reject null hypothesis H0.

Thus we conclude that: speeding tickets are given out in different proportions on each day of the week.
