Norman called today to say he had found a way for us to model the
number of customer phone calls per hour. He had been thinking about
other statistical factors that might play into our planning, so he got out
some of his old stats texts and started browsi
Question 1: When our test statistic does NOT fall into the critical region, why do we say
that we "Fail to reject the Ho" rather than just saying we accept the Ho?
When we fail to reject the H0, were saying that we dont have enough evidence to determine

1. What is the difference between saying that you should get "heads" about half the time
when flipping a "fair" coin and the actual probability of getting 10 heads in 20 flips?
The actual probability of getting 10 heads in 20 flips is computed by:
10/20 =

Where in your experience have you seen regressions applied?
Given a set of data, plotted on a graph, the line will give you the best approximation of the given

One of the most common real world examples of a game tree is the infamous 9 box strategy game called Tic Tac Toe. As we all know, this is a standard two player game that require the use of, "X's for one player, and "O's" for the second player. The idea is
I've selected Google Maps as my real world application of the graph theory. I think this example is more practical and real world due to it's everyday use by millions of people daily and frankly, Google Maps is just a big graph. Of course we all know that
To find out whether how many permutation or combination you can get from a hand of 5 cards
from a deck of cards (52 in total) is first done by determining the formula commonly used to

What is an argument? What is a tautology?
An argument is a sequence of statements that end with a conclusion.
A tautology is a compound proposition that is always true, regardless what the truth values of the propositional variables are.
