200 students were randomly sampled from a community college and 82 of them answered "yes" to the question "do you get enough sleep each night?" A college newspaper states that half (50%) of students get enough sleep each night.  Suppose that we want to test this claim to determine whether it is accurate, and assume that the standard error is 0.0353.

Question

200 students were randomly sampled from a community college and 82 of them answered "yes" to the question "do you get enough sleep each night?" A college newspaper states that half (50%) of students get enough sleep each night.  Suppose that we want to test this claim to determine whether it is accurate, and assume that the standard error is 0.0353.

Step 1: Define the null model.
You need the null value, and the standard error (SE) of any estimate that might come from this
null model with the given sample size for the sample. Label the curve below with the values
that are specific to your hypothesis test.

Step 2: Compute or locate the observed sample statistic.
Determine where it falls on the null distribution. Mark this on the distribution above. The
observed sample statistic is
Step 3: Compute a test statistic:
observed statistic - null value
Test Statistic =
SE
Step 4: Use the test statistic as another way to visualize the agreement
between what you have in the data, and the null model.
Mark the location of the test statistic on the standardized distribution below.
