Researchers collected data on the numbers of hospital admissions resulting from motor vehicle crashes, and results are given below for fridays on the 6th of a month and fridays on the following 13th of the same month. use a 0.05 significance level to test the claim that when the 13th day of a month falls on a friday, the numbers of hospital admissions from motor vehicle crashes are not affected. friday the 6th: 99 66 1010 1010 33 44 friday the 13th: 1414 1313 1313 99 55 1212 what are the hypotheses for this test? let muμsubscript dd be the mean of the differences in the numbers of hospital admissions resulting from motor vehicle crashes for the population of all pairs of data. h00: muμsubscript dd equals= 0 h11: muμsubscript dd not equals≠ 0 find the value of the test statistic. tequals=nothing (round to three decimal places as needed.) identify the critical value(s). select the correct choice below and fill the answer box within your choice. (round to three decimal places as needed.) a. the critical value is tequals=nothing. b. the critical values are tequals=plus or minus±nothing. state the result of the test. choose the correct answer below. a. there is sufficient evidence to warrant rejection of the claim of no effec
