HWK 8: Statistical Inferencea. You have the following data of wind speed (in mph) in Ithaca, NY at 3 pmeach day:10, 7, 3, 9, 7, 10, 12, 13, 1, 12.Evaluate whether this data is a better match for the normal or lognormaldistribution using the Chi Square test, the Maximum Likelyhood test, and theKalmogorov-Smirnoff test. Use the winning distribution to predict theprobability of getting wind speeds over 15 mph. It is recommended you useR for these calculations, but show what you are doing in yourhwksubmission.

Solution: Given data x=c(10,7,3,9,7,9,12,13,1,12) By using R-software…

Answered: a. You have the following data of wind…

Ryan is throwing a football through a tire in his backyard. He has the probability of .30 of throwing the ball through the tire on each attempt, and each attempt is independent of the one before. Draw the graph of the PDF for the first five attempts. What does the graph tell you about the mean and standard deviation?

Assume that the wavelengths of photosynthetically active radiations (PAR) are uniformly distributed at integer nanometers in the red spectrum from 640 to 665 nm. What is the mean and variance of the wavelength distribution for this radiation? Round your answers to one decimal place (e.g. 98.7). Mean = i Variance = i
The average amount of time until a car accident on a particular 60 mile stretch of road is 30 minutes. Assume(unreasonably) that car accidents are independent, the time to a car accident is exponentially distributed, and that two accidents cannot occur at the same time. a. What is the probability of a car accident occurring in the first hour?b. What is the probability of a car accident occurring between 15 and 45 minutes? c. What is the variance of the time until a car accident occurs? If a car accident has not happened in 2 hours, what is the probability it will happen in the next hour?
