A Registration - Paym.. R6.1. Knees Patients receiving artificial knees of experience pain after surgery. The pain is measured on subjective scale with possible values of 1 (low) to 5 (hig Let X be the pain score for a randomly selected patient. T following table gives part of the probability distribution for Value: Probability: (a) (b) (c) 1 0.1 2 0.2 3 4 0.3 0.3 5 77 Find P(X= 5). If two patients who received artificial knees are cho- sen at random, what's the probability that both of them report pain scores of 1 or 27 Show your work. Compute the mean and standard deviation of X Show your work

Which one of the following statements is True? The Odds against A equals 1 – Odds in favor of A. For a mound shaped distribution if the skew is positive then the mean is greater than the median. P(n, r) = C(n, r) / r! The probability of an event equals the number of favorable outcomes divided by the number of unfavorable outcomes. A Bimodal distribution is symmetric.

Determine the required value of the missing probability to make the distribution a discrete probability distribution. P(4) = (Type an integer or a decimal.) X P(x) 3 0.16 4 ? 5 0.40 6 0.15 ...
