If you choose one of the hypothesis tests, you can choose
an alternative hypothesis to test against the null
hypothesis. For each test, there are three possible choices
Z-Int: 1 π The confidence interval for one
proportion, based on the
Normal distribution
Z-Int: π
1
– π
2
The confidence interval for the
difference between two
proportions, based on the
Normal distribution
T-Int: 1 μ The confidence interval for one
mean, based on the Student's t-
distribution
T-Int: μ
1
– μ
2
The confidence interval for the
difference between two means,
based on the Student's t-
distribution
Χ 2 test
Goodness of fit The chi-square goodness of fit
test, based on categorical data
2-way test The chi-square test, based on
categorical data in a two-way
table
Regression
Linear t-test
The t-test for linear regression
Interval: Slope The confidence interval for the
slope of the true linear
regression line, based on the t-
distribution
Interval: Intercept The confidence interval for the
y-intercept of the true linear
regression line, based on the t-
distribution
Interval: Mean
response
The confidence interval for a
mean response, based on the t-
distribution
Prediction interval The prediction interval for a
future response, based on the t-
distribution
