8-5 Hypothesis Tests: Claims about a Mean μ

distpic_z.gifTo test a claim about μ, use a t distribution Table A-3

Examples of claims (hypotheses) about a mean, μ that can be tested:

Original claim (English) Original claim (math)
The mean body temperature of healthy adults is not 98.6 degrees Fahrenheit. μ ≠ 98.6
The mean weight of nicotine per cigarette is at most 40 milligrams. μ ≤ 40
Ball bearings produced by a factory have a mean weight of 436 grams. μ = 436
The mean waiting time at a restaurant is at least 15 minutes. μ ≥ 15

Technique to be learned: Perform a hypothesis test for a claim about a mean of a single population.
