Suppose you want to test the claim that a population mean equals48.

(a) State the null hypothesis.

H₀:>48

H₀:<48

H₀:= 48

H₀:48

H₀:48

(b) State the alternate hypothesis if you have no information regarding how the population mean might differ from48.

H₁:>48

H₁:<48

H₁:= 48

H₁:48

H₁:48

(c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed48.

H₁:>48

H₁:<48

H₁:= 48

H₁:48

H₁:48

(d) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than48.

H₁:>48

H₁:<48

H₁:= 48

H₁:48

H₁:48
