Problem 3

Questions 15 refer to the sample data in the following table (based on data from the Bureau of Labor Statistics). The table lists frequencies for randomly selected nonfatal occupation injuries arranged according to day of the week. Assume that we want to use a 0.05 significance level to test the claim that such injuries occur with equal frequency on different days of the week. Day Mon Tues Wed Thurs Fri Number 23 23 21 21 21 Is the hypothesis test lefttailed, righttailed, or twotailed?

Step-by-Step Solution:
Step 1 of 3

Elementary Statistics Notes Amanda Selly 8/26/2016 We obtained this set of data by dropping a pen seven times to see where it lands {3,4,3,2,4,3,4,2,4,4,5,2,4,4,2,2,5,2,6,3,2,4,4,3,2,1,3} So obviously this set of numbers doesn't really mean anything to us and we can't get any information about it this way so we make a Frequency Table: Value Frequenc Relative y Frequency 0 0 0/28 1 1 1/28 2 8 8/28 3 7 7/28 4 9 9/28 5 2 2/28 6 1 1/28 7 0 0/28 Total N=28 N is representative
