A neurologist is testing the effect of a drug on response time by randomly injecting 100 rats with a unit dose of the drug, subjecting each to neurological stimulus, and recording its response time. The neurologist knows that the mean response time for rats not injected with the drug is 1.2 seconds, and it is of interest whether a unit dose of the drug will affect the response time of a rat. The neurologist plan to conduct a hypothesis test at a = 0.01 using a 99% confidence interval based on the following information about the collected sample: 1. Sample size:n = 100, 2. Sample mean of 100 observations: = 1.05 %3D 3. Sample standard deviation: sd = 0.5. Suppose you would use t-distribution to construct a confidence interval for the mean response time. Fill in the following blanks using dropdown windows: 1. What is the point estimate (center) of the 99% confidence interval? [ Select ] 2. What is the estimated standard error of the sample mean? [ Select ] 3. What is the critical value required by our significance level a = 0.01. %3D [ Select ]

Question
A neurologist is testing the effect of a drug on response time by randomly injecting 100 rats with a unit dose of the drug, subjecting each to neurological stimulus, and recording its response time. The neurologist knows that the mean response time for rats not injected with the drug is 1.2 seconds, and it is of interest whether a unit dose of the drug will affect the response time of a rat. The neurologist plan to conduct a hypothesis test at a = 0.01 using a 99% II confidence interval based on the following information about the collected sample: 1. Sample size: n = 100, 2. Sample mean of 100 observations: x = 1.05 3. Sample standard deviation: sd = 0.5. Suppose you would use t-distribution to construct a confidence interval for the mean response time. Fill in the following blanks using dropdown windows: 1. What is the point estimate (center) of the 99% confidence interval? [ Select ] 2. What is the estimated standard error of the sample mean? [ Select ] 3. What is the critical value required by our significance level a = 0.01. %3D [ Select )
