Question

Question 4 (20 points, 5 points each) Identify whether following statements are True or False: a- The standard normal distribution has taller peak and thicker tails than t distributions. b- If a confidence interval for comparing two means includes zero, we would fail to reject the null hypothesis. c- The Normal approximation to the sampling distribution of p? is most accurate when p is close to 0 or 1. d- The chi-square statistic could be interpreted as a measure of the distance between the observed counts and the expected counts.
