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?

The life span of Duracell batteries is normally distributed. The mean life span is 10,502 hours an the standard deviation is 415 hours. If 66,500 duracell batteries are manufactured, approximately how many of those batteries last at least 9,850 hours? A 39,900 B. 46,600 C. 59,900 D. 62,600
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.

A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 4 stan deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have n length of 14 cm with a standard deviation of 0.05 cm. For what lengths will a bolt be destroyed? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) OA. A bolt will be destroyed if the length is less than OB.
