Mgeb12 quantitative methods in economics ii - ass1 solution. Problem 1 (a) from output 95% 2-sided c. i: 72 2. 4768 72 + 2. 4768 so 69. 5232 74. 4768 so should not launch drink. (b) for a 80% c. i. 100(1- ) = 80 get = 0. 2, d. f. C. i. is 72 1. 816 or 70. 4184 73. 5816 tp. From t-dist table get t24,0. 1 = 1. 318 (c) Reject ho if t0 -t /2 or t0 t /2 t m. P[t24 t24,. 005] = 0. 005 get t24,. 005 = 2. 797. Reject ho if z0 z , test statistic. Therefore fail to reject ho or commit type ii error if x < 77. 325. = p[ x < 77. 325] = p[ x 77. 325] due to x is continuous rv. ] = p[ x s m a n. = 0. 01 find p[z z ] = p[z z0. 01 ] = 0. 01 p[z z0. 01] = 0. 99 get z0. 01 = 2. 325.
