Let the random variable X represent the profit made on a randomly selected day by a certain store. Assumethat X is approximately Normal with mean $360 and standard deviation $50. The most profitable 10% of dayshave a profit of at least how many dollars?(a) $244(b) $296(c) $370(d) $424(e) $4768. Which of the following is a true statement?(a) The binomial setting requires that there are only two possible outcomes for each trial, while thegeometric setting permits more than two outcomes.(b) A geometric random variable takes on integer values from 0 to n.(c) If X is a geometric random variable and the probability of success is 0.85, then the probabilitydistribution of X will be skewed left, since 0.85 is closer to 1 than to 0.(d) An important difference between binomial and geometric random variables is that there is a fixednumber of trials in a binomial setting, and the number of trials varies in a geometric setting.(e) The distribution of every binomial random variable is skewed right.Use the following for problems 9 and 10.
