1 The state of New York reported 1484 live births in which the infants had Down syndrome (trisomy 21) between 2006 and 2010, which averages to about 5.7 cases per week. While the causes of Down syndrome are not fully understood, it is reasonable at this point to assume that live births are independent and the weekly rate is constant. Let X be the count of babies born with Down syndrome in the state of New York in a given week. 1. C. T. Mai et al., "Selected birth defects data from population-based birth defects surveillance programs in the United States, 2006 to 2010: Featuring trisom conditions," Birth Defects Research, 97 (2013), pp. 709-725. What is the probability that 10 or more children are born with Down syndrome in a given week? Give your answer to four decimal places. P(X ≥ 10) =

Section F: In a random sample of 150 unemployed males, 81 of them stated that they were regular consumers of alcoholic beverages. Let p denote the true proportion of unemployed males that are regular consumers of alcoholic beverages.

A particular report included the following table classifying 816 fatal bicycle accidents that occurred in a certain year according to the time of day the accident occurred. Time of Day Number of Accidents midnight to 3 a.m. 46 3 a.m. to 6 a.m. 50 6 a.m. to 9 a.m. 85 9 a.m. to noon 72 noon to 3 p.m. 79 3 p.m. to 6 p.m. 157 6 p.m. to 9 p.m. 193 9 p.m. to midnight 134 For purposes of this exercise, assume that these 816 bicycle accidents are a random sample of fatal bicycle accidents. Do these data support the hypothesis that fatal bicycle accidents are not equally likely to occur in each of the 3-hour time periods used to construct the table? Test the relevant hypotheses using a significance level of a = 0.05. Let P1. P2: P3: P4 Ps: Pe: P7, and Pg be the proportions of accidents occurring in the eight different time periods. State the appropriate null and alternative hypotheses. O Ho: P1 = P2 = P3 = P4 = Ps = P6 = P7 = Pg = 816 H: Ho is not true. O Ho: P1 = P2 = P3 = P4 = P5 = P6 = P7 =…

The null hypothesis when testing for a single population can take many forms depending on the parameter being studied.  If the parameter of interest is the population mean, which statement best represents the original claim that the parameter equals a given value, k?
