WebThe T-Distribution or student T-Distribution forms a symmetric bell-shaped curve with fatter tails. Its mean comes out to be zero. The value of the distribution ranges between -∞ and ∞. Its variance is computed as v/ (v-2). Here, v ≥ 2 and ‘v’ denotes the degree of freedom: ‘Var (t) = v/ (v -2)’. The variance values are higher ...

WebSolution: To find the z-score, we use the formula: z = (x - mean) / standard deviation. Plugging in the values, we get: z = (70 - 65) / 3 = 1.67. The z-score for a student who is 70 inches tall is 1.67, which means that this student's height is 1.67 standard deviations above the mean height of the group. Problem 2:
