Suppose you want to test the claim that a population mean equals40.

(a)State the null hypothesis.

H₀:>40

H₀:<40

H₀:= 40

H₀:40

H₀:40

(b)State the alternate hypothesis if you have no information regarding how the population mean might differ from40.

H₁:>40

H₁:<40

H₁:= 40

H₁:40

H₁:40

(c)State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed40.

H₁:>40

H₁:<40

H₁:= 40

H₁:40

H₁:40

(d)State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than40.

H₁:>40

H₁:<40

H₁:= 40

H₁:40

H₁:40
