Write a program that uses an array of high temperatures for your
hometown from last week (Sunday – Saturday). Write methods to
calculate and return the lowest high temperature (minimum) and a
method to calculate and return the highest high temperature
(maximum) in the array. You must write YOUR ORIGINAL methods for
minimum and maximum. You MAY NOT use Math class methods or other
library methods.
Write an additional method that accepts the array as a parameter
and then creates...

6. Listed below are actual high temperatures and the high
temperatures that were forecast five days earlier. Use a .05
significance level to test the claim of a zero mean difference
between the actual high temperatures and the high temperatures that
were forecast one day earlier. Use our 4-step procedure. This is a
matched or paired samples hypothesis test. Actual high: 80 77 81 85
73 High forecast one day earlier: 78 75 81 85 76
