Question

A rival company, We Be Education Company (WBEC), is also trying to develop a similar product which cost US$5,000 per year. Their researchers took a random sample of 81 students from a school district that had a mean reading comprehension score of µ = 400 with a standard deviation of 100. After using the product for two semesters the mean reading comprehension scores for these 81 students was M = 419, z = 1.71, d = .19. Based on the obtained z value for the above WBEC study and an ⍺ level of .05, do they have sufficient evidence to reject their null hypothesis?
