Activity Overview
In this activity, students evaluate hypotheses.
Before the Activity
See the attached PDF file for detailed instructions for this activity
Print pages 89 - 100 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the Activity procedures:
Testing Hypothesis of a Population Mean:
Store the data as a list
Calculate the z value if the standard deviation is known, else find the t value
Check whether the t or z values are positive or negative
Determine the p-value and evaluate the hypothesis
Testing Hypothesis of a Population Proportion:
Decide if you can use a normal distribution to approximate the binomial
Enter the values
Calculate the z-score
Determine the p-value and evaluate the hypothesis
Testing Hypothesis of a Normal Population Standard Deviation:
Enter the data
Realize that if the data is normally distributed, the sampling distribution is chi-square distributed
Determine the left-tail probability of the chi-square distribution [the p-value]
Evaluate the hypothesis on the basis of the p-value
Testing Hypothesis of Two Population Means:
Store the data as lists
Enter the values for means, standard deviations, and sample sizes
Perform a two-sample T test, if the standard deviations are known
Perform a two-sample Z test, if the standard deviations are unknown
Determine the p-value and evaluate the hypothesis
Testing Hypothesis of Two Population Proportions:
Enter the values to calculate the proportion
Determine the p value to evaluate the hypothesis
Calculate the pooled proportion and the standard score
Testing Hypothesis of Standard Deviations of Two Normal Populations:
Sort the data and store it in lists
Determine the p and F values and evaluate the hypothesis
After the Activity
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
