MATLAB Problems: 1) For f (x) = e^(-|x|) on [-3, 3], you are to compare evenly-spaced interpolation with Chebyshev interpolation. In this exercise, you do not have to use any loops. b) Modify your script from part (a) to make a new script file to do the following: Compute the n Chebyshev nodes, and call newtdd.m and nest.m the same way you did in part (a) to get an interpolating polynomial on x-values evenly spaced by 0.01 between -3 and 3. Plot the new interpolating polynomial, and also plot the vector of the absolute errors between the interpolating polynomial and […]

Suppose a bus arrives at a station such that the time between arrivals is exponentially distributed with rate 1/λ. To get home, you decide to wait for the bus for some number of minutes t. If the bus has arrived before t minutes, you take the bus home which takes time B. If the bus has not arrived after t minutes, you walk home which takes time W. (a) What is the expected total time from getting to the bus stop until getting home? (b) Suppose W < 1/λ + B at what value of t is the expected wait […]

In an English Class, the midterm exam raw scores (i.e., the values of x) form a normal distribution, with a mean of 239 and a standard deviation of 37. What percentage of exam scores are more than 1.5 standard deviations of distance away from the mean?

According to the Coffee Research Organization (http://www.coffeeresearch.org) the typical American coffee drinker consumes an average of 3.1 cups per day. A sample of 12 senior citizens revealed they consumed the following amounts of coffee, reported in cups, yesterday. At the .05 significance level does this sample data suggest there is a difference between the national average and the sample mean from senior citizens?
