Question 696636: A bicycle safety organization claims that..........Can you reject that the distirbution is uniform? A bicycle safety organization claims that fatal bicycle accidents are uniformly disturbed throughout the week. The table shows the day of the week for which 779 randomly selected fatal bicycle accidents occurred. At ?=0.10, can you reject the claim that the distribution is uniform?
a) State your Hypothesis, and identify the claim
b) (DATA) Conduct the test and underline your decision
Sunday107
Monday113
Tuesday 106
Wednesday 111
Thursday 123
Friday 106
Saturday 113 T
determine the critical value adn the rejection region calculate teh test statistic and decide whether or not to reject the null hypothesis
please help!!

determine the critical value and the rejection region calculate teh test statistic and decide whether or not to reject the null hypothesis
-------------------------------------------------------
Ho: probabilities are all equal
Ha: at least one of the probabilities is not equal
-----------
I ran a Goodness-of-Fit Test on my TI84 and got the following:
Test statistic: Chi-Sq = 15.99..
p-value: 0.0011..
Conclusion: Since the p-value is less than 10% reject Ho.
