Suppose your waiting time for a bus in the morning is uniformly distributed on [0, 12], whereas waiting time in the evening is uniformly distributed on [0, 14] independent of morning waiting time.(a) If you take the bus each morning and evening for a week, what is your total expected waiting time? (Assume a week includes only Monday through Friday.) [Hint: Define rv's X,, ..., x,g and use a rule of expected value.]min(b) What is the variance of your total waiting time?

Time Frequency 40-49 16 50-59 88 60-69 46 70-79 12 80-89 214 90-99 22 100-109 2 (a) Approximate the mean length of time between arrivals. (b) Approximate the standard deviation of the length of time between arrivals.
Storm damage can occur to homes in any given year, with the amount of damage varying randomly from year to year. Let X represent the dollar value of storm damage in a given year. It is known that in 95% of the years, X = $0, while in 5% of the years, X = $20,000. What is the expected value and standard deviation of the damage in any given year?

Complete parts (a) through (4). m Click the icon to view the data table. OC The plot of the residuals against x tends to cluster as x increases, which is a possible violation of the Linearity Conditon. The Normal probability plot indicates that the Normal Population Assumption is satisfied. OD. The plot of the residuals againat x shows no patten, which satisfes the conditions for linear regression.

List five properties of the F-distribution. Determine the first of the five properties. V and the degrees of freedom corresponding to The F-distribution is a family of curves, each of which is determined by two types of degrees of freedom: the degrees of freedom corresponding to the variance in the numerator, denoted by the variance in the denominator, denoted by
