This post-holiday death peak has been attributed to a number of factors, including the willful postponement of death until after the holiday, as well as holiday stress and post-holiday depression. Writing in the Journal of the American Medical Association (April 11, 1990), Phillips and Smith report that among a total of 103 elderly California women of Chinese descent who died of natural causes within one week of the Har-vest Moon Festival, only 33 died the week before, while 70 died the week after. (a) Using the .05 level of significance, test the null hypothesis that, in the underlying population, people are equally likely to die either the week before or the week after this holiday. (b) Specify the approximate p-value for this test result. (c) How might this result be reported in the literature?ortions described in t 19.16 Test the null hypothesis at the .01 level of significance that the distribution of bloodtypes for college students complies with the proportions described in the blood bank bulletin, namely, .44 for O, .41 for A, .10 for B, and .05 for AB. Now, however, assume that the results are available for a random sample of only 60 students. The results are as follows: 27 for O, 26 for A, 4 for B, and 3 for AB. NOTE: The expected frequency for AB, (.05)(60) = 3, is less than 5, the smallest permissible expected frequency. Create a sufficiently large expected frequency bycombining B and AB blood types. he blood bank bulletin, namely, .44 for O, .41 for A, .10 for B, and .05 for AB.
