Suppose you want to test the claim that a population mean equals 38.
(a) State the null hypothesis.
H0: > 38H0: < 38 H0: = 38H0: ≠ 38H0: ≥ 38
(b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 38.
H1: > 38H1: < 38 H1: = 38H1: ≠ 38H1: ≥ 38
(c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 38.
H1: > 38H1: < 38 H1: = 38H1: ≠ 38H1: ≥ 38
(d) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than 38.
H1: > 38H1: < 38 H1: = 38H1: ≠ 38H1: ≥ 38
