Determine whether the distribution represents a probability distribution. It not, state why. x 20 30 40 50 p(x)1.1 0.2 0.9 0.3 14. State whether the variable is discrete or continuous. The number of people who play the state lottery each day. 5.3 Problem # 19 A person decides to invest \$50,000 in a gas well. Based on history, the probabilities of the outcomes are as follows. Outcome p(x) \$80,000 (highly successful) 0.2 \$40,000 (Moderately successful) 0.7 -\$50,000 (Dry well) 0.1 Find the expected value of the investment. Would you consider this a good investment? 5.4 Problem # 16 16. Find the mean, variance, and standard deviation for the number of heads when 20 coins are tossed. This question is from textbook Elementary Statistics Answer by Fombitz(13828)   (Show Source): You can put this solution on YOUR website!5.2 (10, 14) 10. No, p(x)<=1, p(20)>1. . . . 14. Discrete, the values are only positive integers (0,1,2,3,...). no numbers in between. . . . 5.3 Problem # 19 You put in \$50,000 and get back \$39,000. Doesn't seem like a good investment. . . . Coin flipping is a binomial event (heads or tails). Number of trials(coin flips), n=20 Probability of heads, p=1/2. Mean==10 heads Variance = Standard deviation =
