I really need help with these problems
The police department in Madison, Connecticut released receiving a total of 1095 calls for the different days of the week during a recent February that had 28 days: Monday (114); Tuesday (152); Wednesday (160); Thursday (164); Friday (179); Saturday (196); Sunday (130). Use a 0.01 significance level to test the claim that the different days of the week have the same frequencies of police calls. Is there anything notable about the observed frequencies? Round to four decimal places if necessary. a) Write the hypotheses b) The expected frequency of receiving calls on Monday is The expected frequency of receiving calls on Tuesday is c) significance level: α = d) Test statistic: Clearly state whether test statistic in this claim is z, t, chisq. For example, "chisq=1.2345" e) Compute p-value of the test statistic. f) Decision: Type "yes" if reject null hypothesis. Type "no" if not to reject null hypothesis.
