A researcher wants to know if there is a difference in how busy someone is based on whether that person identifies as an early bird or a night owl. The researcher gathers data from randomly selected people in each group, the higher scores represent higher levels of being busy. Test for a difference between the two at the 10% level of significance. Scores are normally distributed and population variances are assumed to be not equal. 29 Early Bird 23 27 26 30 22 25 27 28 33 19 Solve first for the mean and standard deviation first. Use the standard deviation formula with n-1 as the Night Owl 26 |18 25 22 11 20 26 13 denominator. a. Claim (in symbolic form): Ho: На: b. level of significance: c. Decision Rule: Reject Ho if test-statistic: tail of distribution: d.Computation
