StatisticsAn organizational psychologist is interested in studying whether critical feedback affects employee job performance Critical feedback involves comments about an employee can do better without necessarily commenting on what they are already doing well The company the psychologist works for is considering implementing critical feedback but they want to know what the effect of critical feedback is first They decide to run a small study with 1 randomly selected employee The psychologist hypothesizes that critical feedback will affect that employee s job performance compared to other employees those that do not receive critical feedback The psychologist knows that performance ratings in the company are normally distributed with an average of 5 8 on a 7 point scale with 1 being the lowest and 7 being the highest The standard deviation is 0 65 The psychologist randomly selects a single employee in the company observes the employee s performance and gives the employee critical feedback every week for a month The psychologist then has the employee s manager rate their job performance on the 1 7 scale The employee receives a score of 7 What should the researcher conclude about the effectiveness of critical feedback based on the results of a null hypothesis significance test using this sample of 1 person using the 5 steps of hypothesis testing 05 significance level Calculate the sample s Z score on the comparison distribution report up to 2 decimal places
