A company running online speed reading courses claims that students who take their courses show a 500% (5 times) increase in the number of words they can read in a minute without losing comprehension. A random sample of 100 students yielded an average increase of 453% with a standard deviation of 218%. We want to assess the companies' claim. Assume the conditions for the sample mean being approximately normal are satisfied. (a) Perform a hypothesis test evaluating if the company's claim is reasonable. Use a significance level of a = 0.05 and calculate a p-value and report it to 3 significant figures. At the end, make sure to interpret your response (in one sentence) in the context of the hypothesis test and the data. [5] (b) Calculate a 95% confidence interval for the average percentage increase in the number of words students can read in a minute without losing comprehension. [2] (c) Do your results from the hypothesis test and the confidence interval agree? Explain why (in one sentence). [1] CW 20.2. Find the sample mean. You are given the following hypotheses: Ho: / = 35, HA: u > 35. We know that the sample standard deviation is 10 and the sample size is 81. For what sample mean would the p-value be equal to 0.05? Assume that all conditions necessary for the sample mean to be nearly normal are satisfied. [3] 9.C 15:05 Light rain W 16/03/2022
