Question

Researchers examined the number of people admitted to emergency rooms for vehicular accidents on 12 Friday evenings (6 each on the 6th and 13th).

Year Month 6th 13th

1989 October 9 13

1990 July 6 12

1991 September 11 10

1991 December 11 13

1992 March 3 2

1992 November 5 12

From there, the following summary statistics were found: d= 2.83 Sd=3.43

Is there enough evidence to suggest that significantly more people are admitted to emergency rooms on Friday the 13th? Use alphaα = 10%. *

While I hope you have an appropriate null and alternative in mind while running through this hypothesis test, for today I will not be asking you what that is.

Find the correct test statistic. Round to three decimal places.

Find the df: Find the p-value: Round to four decimal places.

Write the conclusion in context: There (choose one: is/is not) enough evidence to suggest that significantly more people are admitted to emergency rooms on Friday the 13th.
