3.The braking distance for a Krazy-Car traveling at 50 mph is normally distributed with a mean of50 ft. and a standard deviation of 5 ft. Answer the following without using a calculator or atable.• What is the likelihood a Krazy-Car will take more than 65 ft. to stop?• What is the probability a Krazy-Car will stop between 45 ft. and 55 ft.?• What percent of the time will a Krazy-Car traveling at 50 mph stop between 35 and 55 ft.?• What is the probability a Krazy-Car will require less than 50 ft. or more than 60 ft. to stop?

A vendor converts the weights on the packages she sends from pounds to kilograms (1 kg ≈ 2.20 lb). The mean weight of the package was 21 lb with standard deviation of 0.31 lb. After repackaging (converting units), the mean becomes kg (round your answer to 2 decimal places), and the standard deviation becomes kg (round your answer to 2 decimal places).

A ski gondola carries skiers to the top of a mountain. Assume that weights of skiers are normally distributed with a mean of 193 Ib and a standard deviation of 37 lb. The gondola has a stated capacity of 25 passengers, and the gondola is rated for a load limit of 3750 lb. Complete parts (a) through (d) below. a. Given that the gondola is rated for a load limit of 3750 lb, what is the maximum mean weight of the passengers if the gondola is filled to the stated capacity of 25 passengers? The maximum mean weight is lb. (Type an integer or a decimal. Do not round.) b. If the gondola is filled with 25 randomly selected skiers, what is the probability that their mean weight exceeds the value from part (a)? The probability is. (Round to four decimal places as needed.) c.

A distance is measured six times. The observed values are 572.182 m, 572.140 m, 572.103 m, 572.160 m, 572.125 m, and 572.155 m. All measurements are uncorrelated and their standard deviations are 0.030 m, 0.030 m, 0.030 m, 0.020 m, 0.020 m, and 0.010 m, respectively. Find the least squares estimate for the distance. Use matrices and R in the solution. Write the R commands involved.
