A) A particular report from 2004 classified 718 fatal bicycle accidents according to the month in which the accident occurred, resulting in the accompanying table. January 38 March 43 April 60 May 79 June 73 July 97 August 83 September 63 October 67 November 44 Febuary 31 December 40 Use the given data to test the null hypothesis H0: ?1 = 1/12, ?2 = 1/12, . . . , ?12 = 1/12, where ?1 is the proportion of fatal bicycle accidents that occur in January, ?2 is the proportion for February, and so on. Use a significance level of 0.01. (Use 2 decimal places.) ?2 = (B) The null hypothesis in Part (a) specifies that fatal accidents were equally likely to occur in any of the 12 months. But not all months have the same number of days. Test the hypotheses proposed in H0: ?4 = ?6 = ?9 = ?11 = 30/366 ≈ 0.082, ?2 = 29/366 ≈ 0.085 using a 0.05 significance level. (Use 2 decimal places.)≈ 0.079, ?1 = ?3 = ?5
