3. The numbers of false fire alarms were counted each month at a number of sites. The results are given in the following table. Month Number of Alarms Jan 32 Feb 15 March 37 April 38 May 45 June 48 July 46 Aug 42 Sept 34 Oct 36 Nov 28 Dec 26 Chi-Square Goodness-of-Fit $H_0$: The proportions are as proposed $H_A$: The proportions are different n: 427 df: 11 $\chi^2$ Statistic: 27.791569 P Value: 0.003484 Test the hypothesis that false alarms are not equally likely to occur in any month. Use a 0.01 level of significance and the provided SALT output to conduct the hypothesis test. (a) State the hypothesis. (b) State the test statistic. (Round to 2 decimal places) (c) State the P-value. (Round to 4 decimal places) (d) What is your decision? (e) State a conclusion.
