Q2.4 1 D 2 Points Suppose a one sample 95% t confidence interval for / has been constructed. A second confidence interval for u is constructed from the same data, using a larger sample and a confidence level of 90%. We expect that the width of the second interval is: O Larger than the current interval width O The same as the current interval width O Narrower than the current interval width O Unknown until actual sample sizes are determinedQ4 Problem 3 2 Points Which statement below describes a property of the t statistic of the one-sample t test? O The distribution of the t statistic (t distribution) under Ho has a smaller (i.e. more narrow) spread than a standard normal distribution. O The distribution of the t statistic (t distribution) under Ho depends on n. O The distribution of the t statistic (t distribution) under Ho cannot be estimated unless n is large. O Both A and B
