(a)
To test: The
(b)
To find: The probability that there are no interruptions in a week.
(c)
To find: The average number of interruption in a week.
(d)
To find: The probability that there are no interruptions in a week using Poisson distribution.
To explain: The reason for which the obtained probability in part (b) and part (d) is same.
(e)
To explain: The reason for which the use of the binomial distribution for computing the probability that there is one day which has interruption would not provide the same probability if the calculation is made using the Poisson distribution.

- AP1.1 You look at real estate ads for houses in Sarasota, Florida. Many houses range from $200,000 to $400,000 in price. The few houses on the water, however, have prices up to $15 million. Which of the following statements best describes the distribution of home prices in Sarasota? The distribution is most likely skewed to the left, and the mean is greater than the median. The distribution is most likely skewed to the left, and the mean is less than the median. The distribution is roughly symmetric with a few high outliers, and the mean is approximately equal to the median. The distribution is most likely skewed to the right, and the mean is greater than the median. The distribution is most likely skewed to the right, and the mean is less than the median.arrow_forwardDuring busy political seasons, many opinion polls are conducted.

- 28. (a) Under what conditions do we say that two random variables X and Y are independent? (b) Demonstrate that if X and Y are independent, then it follows that E(XY) = E(X)E(Y); (e) Show by a counter example that the converse of (ii) is not necessarily true.arrow_forward1.
