 Consider the information and analysis. Identify and fix the errors addressed

Consider the information and analysis. Identify and fix the errors addressed below. Market researchers from a tech company are beta testing a new feature on one of their smartphones. A randomly selected sample of phone users are beta testing the new feature for 6 months. They are asked to rate the feature from 1 to 10 in several categories. If the overall average rating is greater than 8.0 they will promote the feature into production. Otherwise, they will continue develop on the feature based on the feedback. The average from the sample of 119 beta testers is 8.17. Researchers assume the population standard deviation is 0.9 and use a significance level of 0.05 to test the average. The null and alternative are: H : x = 8 H : x >8 The test statistic and p-value are: z test statistic = 8.17 - 8 0.9 = 0.189 p - value = 0.0197 Conclusion: There is no evidence the average rating of the new feature is more than 8. We fail to reject the null hypothesis
