Critical values (pt. 1)

Critical values (one group z-test)

Use R to find the following critical values for a one group z-test:

## alpha = 0.05, two-tailed test

## alpha = 0.025, one-tailed test with H_a: x_bar > mu

## alpha = 0.01, one-tailed test with H_a: x_bar < mu

## alpha = 0.01, two-tailed test

## alpha = 0.05, one-tailed test with H_a: x_bar < mu
