The estimated confidence interval for ẞ2 at 95% confidence level is [0.00, 0.80]. Based on this estimate, which of the following statements is FALSE: (a) We can reject the hypothesis Ho: ẞ2 = 1 versus Ho: ẞ2 #1 at 5% significant level. (b) The p-value for the hypothesis testing of Ho: ß₂ = = 0.80 versus Hoẞ2 0.80 is 5%. (c) The estimate for 2 is the center of the interval. (d) We cannot reject the hypothesis Hoẞ2 = 0.1 versus Ho: ẞ2 0.1 at 5% significant level. (e) The true parameter 2 lies in the interval [0.00, 0.80] with probability 95%.
