Question

True or False Areas within continuous probability distribution represent probabilities. True or False The total area within a continuous probability distribution is equal to 100. True or False The total area within any continuous probability distribution is equal to 1.00 True or False For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed. True or False For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed. Use the following to answer questions 21-23: A major credit card company has determined that customers charge between dollar 100 and dollar 1100 per month. Given that the average monthly amount charged is uniformly distributed, answer the following questions. What is the average monthly amount charged? dollar 600 dollar 700 dollar 800 dollar 900 What is the standard deviation of the monthly amount charged? 250 288.67 291.5 301.76 What percent of monthly charges are equal to dollar 500? ______ 31 percent 24 percent 43 percent Cannot calculate with a continuous distribution.

Explanation / Answer

16) True. Area withing continuous distribution is the valu of cumulative probability.

17) False. Area witihin a continuous distribution is equal to probability of 1

18) True. Area witihin a continuous distribution is equal to probability of 1

19) False. In a contiuous distribution, probability of a discrete variable cannot be calculated. It only gives cumulative probability.

20. True. Since it is a discrete distribution
