Suppоse yоu wаnt tо know if the аverаge time it takes to complete a certain task is significantly different from a target time of 30 minutes. You randomly select a sample of 20 participants and time how long it takes them to complete the task. The data is as follows: 26; 29; 31; 33; 27; 28; 30; 31; 32; 29; 25; 28; 34; 30; 31; 27; 29; 33; 28; 30 a) [6 points] What assumptions you need to compute a t confidence interval? Can you built a Z confidence interval, Explain your answer? b) [3 points] Provide a point estimate of the population mean. c) [3points] Regardless of whether or not you think the assumptions are satisfied, construct a 95% confidence interval. Interpret the interval. d) [12 points] Is there sufficient evidence that mean time has increased since ? (1) Write down the null and alternative hypotheses; (2) compute the test statistic; (3) compute the p-value; (4) draw a conclusion.
