The TCS Management Group selected 100 clients randomly and sent them a survey to complete regarding their satisfaction with dealings with TCS. In this survey people were asked about the level of satisfaction where a higher score was indicative of a higher level of satisfaction with possible scores ranging from 0 to 100. The average scores of the sample was 72.44 with a standard deviation of 8.18. Management expects the mean survey score to be at least 70. Provide a hypothesis test, at a 5% significance level, to test if the population mean survey score is at least 70. (Hint: Implement all steps.)
