The table below displays the number of accidents recorded at a particular intersection during each of the four seasons last year:
Season Spring Summer Fall Winter no. of accidents 13 24 18 25
We would like to conduct a chi-square goodness-of-fit test to determine whether accidents are uniformly distributed over the four seasons.The value of the test statistic for the appropriate test of significance is?
I'm not quite sure how to proceed with this one.. Binomial distribution would not work, I think, since it's asking for a uniform distribution. How would I compute p-hat?
