Assume that a measure of stress is known to have a mean of 50 and a SD of 10 in a general population of adults. A sample of 100 inpatients had a mean of 53. Do the inpatients differ from the known population on stress? 5-2-1. What is the null hypothesis? Ⓒμ = 50 μ = 50 u=53 Ⓒu +53 O x = 50 0 x 50 ⒸX-53 x 53
5-2-1b. What is the "default" alpha (if it's not explicitly stated)? 01, one-tailed .01, two-tailed .05, one-tailed .05, two-tailed
5-2-1c. Based on the scenario in 5-2-1, what is the standard error of the known population? 1 10 50 53 can't be determined
The remaining questions are based on the scenario from 5-2-1. 5-2-2. What is the value of the z-statistic you would compute to assess the likelihood the sample was drawn from the target population? 0.03 .3 01 3
5-2-3. What would your statistical conclusion be? Reject Ho Fail to reject Ho Accept Ho Accept HA
