Suppose you want to test the claim that a population mean equals 40. (a) State the null hypothesis. H 0 : μ > 40 H 0 : μ  40 H 1 : μ


Suppose you want to test the claim that a population mean equals 40.


(a) State the null hypothesis.


H
0: μ > 40


H
0: μ <>


H
0: μ = 40


H
0: μ ≠ 40


H
0: μ ≥ 40


(b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 40.


H
1: μ > 40


H
1: μ <>


H
1: μ = 40


H
1: μ ≠ 40


H
1: μ ≥ 40


(c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 40.


H
1: μ > 40


H
1: μ <>


H
1: μ = 40


H
1: μ ≠ 40


H
1: μ ≥ 40
