5) (4.5 pts) For the next set of questions, you must either identify your response by bolding/ or highlighting available options or indicating TRUE or FALSE. a) (1.5 pts) If E(B1} - B1 = 0, then B, is a(n) (biased/unbiased) estimator of B1. (bold or highlight one). b) (1.5 pts) It is possible to observe a correlation coefficient value of r = 0 when a non-linear relationship between to quantitative variables X and Y is present (TRUE/FALSE) c) (1.5 pts) r will be an unbiased estimator of p as long as the sample size is greater than 30 (TRUE/FALSE)
