a. Construct a 99% confidence interval estimate for the population mean MPG for this type of vehicle, assuming a normal distribution.The 99% confidence interval estimate is from
MPG to MPG. (MPG) Miles per gallon.
(Round to one decimal place as needed.)
b. interpret the interval of (a)

The speed limit of a road is 65 miles per hour. The speed of a car on the highway follows a normal distribution with a mean of 70 and standard deviation of 5. What percent of the distribution breaks the speed limit?
The speed limit of a road is 65 miles per hour. The speed of a car on the highway follows a normal distribution with a mean of 70 and standard deviation of 5. A police officer will only react to speeding if the person is going 3 standard deviations above the average (z = 3). What is the speed at which he will react?

A delivery truck costing $26,000 is expected to have a $1,500 salvage value at the end of its useful life of four years or 125,000 miles. Assume that the truck was purchased on January 2. Calculate the depreciation expense for the second year using each of the following depreciation methods: (a) straight-line, (b) double-declining balance, and (c) units-of-production. (Assume that the truck was driven 28,000 miles in the second year.) Round all answers to the nearest dollar.
a. Straight-line $ ?
b. Double-declining balance $ ?
c. Units-of-production $ ?

In automobile mileage and gasoline-consumption testing, 6 automobiles were road tested for 300 miles in both city and highway driving conditions. The following data were recorded for miles-per-gallon performance. City 16.2 16.7 15.9 14.4 16 16.2 Highway 19.4 20.6 18.3 18.6 18.6 18.7 Use mean, median, and mode to make a statement about the difference in performance for city and highway driving. Which area of Statistics helps you to either validate or disprove such a statement and why?

Three small airplanes flight a 1000-mile route. Write a program
that inputs the airplane make,
model, and the number of gallons of fuel used by each airplane.
After calling a calcMPG()
function once for each airplane have main determine and display
which airplane is the most
fuel-efficient, and how many miles per gallon it got. The calcMPG()
function should be passed
the distance flew and the gallons of gas consumed as arguments and
should return the miles
per gallon obtained. Code must be written in C++

A four-lane urban freeway is rolling on rolling terrain with 12-ft lanes, obstructions 2-ft from the right edge of the traveled pavement, and nine ramps within three miles upstream and three miles downstream of the midpoint of the analysis segment. The traffic stream consists primarily of commuters. A directional weekday peak-hour volume of 2400 vehicles is observed with 800 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and buses and recreational vehicles, determine the level of service.

A six-lane freeway with three lanes in each direction has regular weekday users. The
lanes are 12 feet wide, the right-side shoulder is 2 ft wide, and there are two ramps
within 3 miles upstream and two ramps within 3 miles downstream of the segment
midpoint. The highway is on rolling terrain with 12% large trucks and buses and 2%
recreational vehicles. The peak hour factor is 0.85. Determine the maximum hourly
volumes that can be sustained at LOS C and LOS D densities.

Regarding the notion of organizational culture, structure and styles of management from the perspectives of Handy’s (1976) and Miles & Snow (1978). These authors provided their frameworks that are different from each other’s. What you have to do:
Take an organization with which you are familiar or imaginary organization and evaluate & relate or apply Handy’s and Miles & Snow’s typologies (scientific/logical classification/steps of organizational culture, structure and styles) that they provided in their approaches or framework.
Note: Your conversation must have to reflect your critical thinking and analytical skills.
