In this section you learned how probabilities for continuous random variables correspond to area under a probability distribution curve over a particular interval.   We start this chapter with the uniform distribution because the area under a uniform distribution curve will always be in the shape of a rectangle and the formula for the area […]

In this section you learned how to compute the mean and standard deviation for a binomial random variable.   Fill in the formulas for the mean and standard deviation of a binomial random variable:   For a binomial distribution:  ______________________ and ______________________   You can draw the binomial histograms using StatCrunch.  Use ___Stat____, Calculators___________, ______.  […]

In this section you learned about binomial random variables and the functions binompdf and binomcdf.   An experiment is a binomial experiment if the following conditions are met:   1.            Fixed ________ _____ _______________, n.   2.            The n trials are __ are independent, which […]

In this section you learned the basics of probability.   Looking at page 130 in your book, fill in the following:  ___ ______________________________ are probabilities calculated after information is given.  This is where you want to find the probability of ___________________ event A happening after you know that event B has happened   The notation […]

In this section you learned about random variables and discrete probability distributions.   •             In this section we learned about random variables.  Fill in the definition:   Random variable:  _____________ Random variables are usually denoted by capital letters such as X.  We usually use the abbreviation rv to stand for […]

In this section you learned some more probability rules.   What does it mean to say you have “equally likely outcomes”?                    What is the formula for the Equally Likely Rule   What is the formula for the Complement Rule? _______________________   What are the formulas for […]

In this section you learned the basics of probability.   What is the definition of “probability”?    Given that definition, explain how you know that you must have done something incorrectly if you compute a probability and get an answer of 32/15?   Use your TI84 calculator to simplify the fraction 1592/6898.        […]

In this section you learned how to summarize quantitative data with a measure of spread.   What 3 measures of spread were discussed in this section of the book?   1.            __________________                2.            __________________          […]

In this section you learned how to compute a confidence interval and perform a hypothesis test for the difference in proportions.                   In this section you are dealing with _____ __________________ data.                   The symbol for the parameter in […]

In this section you learned how to compute a confidence interval for the mean using T-Test                   In this section you are dealing with ____one sample interval for the mean___________________ data.                   The symbol for the parameter in this […]
