Suppose X1, .. ,XM are independent, identically distributed random variables with mean a and variance b2. Let aM ≡ (1/M)Σi=1M aM and bM2≡ (1/(M-1)) Σi=1M (Xi-aM)2. a) Show that aM is an unbiased estimator of E[X]: that is, E[aM] = a. b) Assume that the identity E[ Σi=1M (Xi-aM)2 ] = (M-1) b2 is correct. Show that bM2 is an unbiased estimator of var(X): that is, E[bM2] = b2

PSY 230 Flipped Classroom Assignment: Linear Regression GRADED ASSIGNMENT Prompt: After finding an association between openness to experience and interest in statistics, the statistics instructor examined another personality trait: extraversion. Again, he hypothesizes that there would be a positive association between the two variables, such that greater levels of extraversion will be associated with greater levels of interest in statistics. To test this hypothesis, he used the same participants from his course...
