Using the goodness-of-fit test and the 0.01 level of significance, determine whether the accidents are evenly distributed throughout the day.
H0: The accidents are evenly distributed
throughout the day.
H1: The accidents are not evenly distributed
throughout the day.
State the decision rule, using the 0.01 significance level. (Round your answer to 3 decimal places.)
Compute the value of chi-square. (Round your answer to 3 decimal places.)
What is your decision regarding H0?

A number of minor automobile accidents occur at various
high-risk intersections despite traffic lights. The traffic
department claims that a modification in the type of light will
reduce these accidents. The traffic commissioners have agreed to a
proposed experiment. Eight intersections were chosen at random, and
the lights at those intersections were modified. The numbers of
minor accidents during a six-month period before and after the
modifications were as follows:

Problem 8-25
Air pollution control specialists in southern California monitor
the amount of ozone, carbon dioxide, and nitrogen dioxide in the
air on an hourly basis. The hourly time series data exhibit
seasonality, with the levels of pollutants showing patterns that
vary over the hours in the day. On July 15, 16, and 17, the
following levels of nitrogen dioxide were observed for the 12 hours
from 6:00 A.M. to 6:00 P.M.
