Fill in the following as you work through your given problems in MyOpenMath   1.            This is an example of an (observational study/designed experiment)   If this is an experiment, what variable was controlled by the experimenter?   2.            This is an example of an […]

In this section you learned how to make appropriate graphs when data are collected for a single qualitative variable.   Name the two graphs you learned about in this section:   __________________________ and __________________________   Given a frequency, how do you compute the corresponding relative frequency?   ______________Frequency/(sum of all frequencies ) ___________________________   Fill […]

In this section you got a list of very important vocabulary that we are going to use throughout the entire course.   Define the following:   Individual:    Variable:     Population:   Sample:   Parameter:   Statistics:   In the rest of the course, the type of data will play a key role in what […]

In this section you learned how many things in everyday life can be modeled with a normal distribution.                   All normal curves have two parameters:  _____ and __ ___                   The center of the curve is determined by the […]

In this section you learned about random variables and discrete probability distributions.   •             In this section we learned how to compute probabilities for normally distributed random variables using __________ ______ on the TI84.   •             We also learned how to compute values of the […]

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 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 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 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 […]
