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.05.

3. A particular report included the following table classifying 815 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. 52 6 a.m. to 9 a.m. 85 9 a.m. to noon 72 noon to 3 p.m. 76 3 p.m. to 6 p.m. 157 6 p.m. to 9 p.m. 192 9 p.m. to midnight 135 For purposes of this exercise, assume that these 815 bicycle accidents are a random sample of fatal bicycle accidents. Suppose a safety office proposes that bicycle fatalities are twice as likely to occur between noon and midnight as during midnight to noon and suggests the following hypothesis: Ha: p1 > 1/3, p2>2/3 Ha: p1 ≠1/33, p2=2/3 Ha: p1 =1/3,p2=2/3 Ha: H0 is not true. Ha: p1 >1/3,p2<2/3 x2=______? p-value______? State the conclusion in the problem context. Reject H0. There is convincing evidence to conclude that bicycle fatalities are not twice as likely to…
A geographer studying West Africa would like to know the size of stones in the delta region where the Niger River runs into the Gulf of Guinea. He collects 53 stones and measures the diameter of each, and so obtains the following measurements, in centimeters as seen below in the frequency table. Size (cm) Frequency [0, 2) [2, 4) 17 13 [4, 6) [6, 8) [8, 10) [10, 12) 10 7 4 a. Create a histogram for the measured stones. Include all labels. b. How many stones are larger than or equal to 6 cm?
