Answer 1

Given data is right double arrow 5.13, 4.94, 4.07, 4.63, 5.22, 4.67, 4.15, 4.93, 5.14, 5.44, 5.38, 4.60 mean (data) = 4.86 = x^bar s^2 = var (data) = 0.198: n = 12 (number of sample) and mu = 4.61 (Given) then t = statistic - (x^bar - mu/s/ squareroot 4) = (4.86 - 4.61)/ squareroot 0.198/12 [t = 1.94] and [P - value = 0.04] (ii) data 27,26,25,24,27,28,25,25,25, 28,26,22,28,25,26,27,24,31,28,26,27,27,28 Given, mu = 20 x^bar = mean (data) = 26.375, n = 24 s^2 = 3.46 then. t = (x^bar -mu/s/ squareroot n) = (26.375 - 20)/square root3.46/24 [t = 16.78] [P - value = 0] (iii) Given that, x^bar =12.6 (mean of Sample observation) mu = 12.4 S = 4 n = 1000 then, t = (x^bar - mu/s/ squareroot n) = (12.6 - 12.4/4/ squareroot 1000 (t = 1.58) [P - value = 0.0572]
