Suppose we are interested to construct a confidence interval of the mean test score. A random sample of 36 scores is taken and gives a sample mean (sample mean score) of 68. We know that the population standard deviation is 3 points. EBM will be the largest at?

a. for a 66% confidence level

b. for a 95% confidence level

c. for a 99% confidence level

d. for a 90% confidence level

We use the t distribution to construct a confidence interval for the population mean when the underlying population standard deviation is not known. Under the assumption that the population is normally distributed, find tα∕2,df for the following scenarios. Use Table 2. (Round your answers to 3 decimal places.) tα/2,df a. A 90% confidence level and a sample of 13 observations. b. A 95% confidence level and a sample of 13 observations. c. A 90% confidence level and a...
