Based on the confidence interval, can one reject 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? A. NoNo, because the confidence interval includesincludes zero. B. YesYes, because the confidence interval includesincludes zero. C. NoNo, because the confidence interval does not includedoes not include zero. D. YesYes, because the confidence interval does not includedoes not include zero.

complete question:

Researchers collected data on the numbers of hospital admjssions res ulting  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 (based on data from "Is Friday the 13th  Bad for Your Health?" by Scanlon et al., British Medical Journal, Vol. 307, as listed in the Data  and Story Line online resource of data sets). Construct a 95% confidence interval estimate of  the mean of the population of differences between hospital admissions on days that are Friday  the 6th of a month and days that are Friday the 13th of a month. Use the confidence interval  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.

-6.5<μd <-0.1

Step-by-step explanation:

The critical value can be found in table A-3 with df = n - 1 = 6 - 1 = 5:  

The margin of error is then:  

E = 2.571*3.011/√6

  = 3.2

The confidence interval then becomes:  

-6.5 = -3.3 - 3.2 = d' - E < μd < d' + E

       = -3.3 + 3.2 = —0.1

When the 13th day of the month falls on Friday, the number of hospital admissions are less than on another day, because the intent)] lies completely below 0.  

its a, i had the same answer, its from study island right

step-by-step explanation:

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450
