Question

The safety director of Honda USA took samples at random from the file of minor accidents and classified them according to the time the accident took place. Using the goodness-of-fit test and the .01 level of significance, determine whether the accidents are evenly distributed (uniform) throughout the day. Write a brief explanation of your conclusion.

Answer 1

Wrong section.

Answer 2

notes on the goodness of fit test is:

http://en.wikipedia.org/wiki/Pearson%27s...

Chi-squared test for given probabilities

data:  x

X-squared = 24.6, df = 7, p-value = 0.0008931

since the p-value is less than 0.01 we reject the null hypothesis and conclude that the number of accidents is not uniformly distributed.

Answer 3

This is the fantasy sports section. I'm guessing that you would do better in the Science and Math section.

Good luck.
