Dr. Elizabeth Caledonia Ashe, an industrial-organizational psychologist, is asked to develop a new program to change worker absenteeism at Intel. Currently, employees in the entire company (population) miss an average of µ=16 days a year. After developing her new program, Dr. Ashe chooses randomly a small software department at the plant to use for her test. She implements her new program and after a year she determines the number of absences by each of the seven employees (n=7). Her results: Days Absent MM =14.43; s = 5.09. Dr. Ashe wants to conduct a two-tailed non-directional test.

You complete the data analysis in JASP and receive the following p value; p = .623. What decision should you make and what does that decision mean? Was there a difference in Dr. Ashe's study?
