An inspector at a lumberyard needs to find out if their kiln dry bulb is the correct temperature. In order to properly dry the lumber, the average bulb temperature needs to be at least 120 degrees Fahrenheit.

He uses a significance level of 0.05. Choose the correct direction of the test and the appropriate sampling distribution. Right-tailed test; z-distribution. O Right-tailed test; t-distribution.
