Suppose you want to test the claim that a population mean equals 38.

(a) State the null hypothesis.

H₀: ? > 38

H₀: ? < 38

H₀: ? = 38

H₀: ? ? 38

H₀: ? ? 38

(b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 38.

H₁: ? > 38

H₁: ? < 38

H₁: ? = 38

H₁: ? ? 38

H₁: ? ? 38

(c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 38.

H₁: ? > 38

H₁: ? < 38

H₁: ? = 38

H₁: ? ? 38

H₁: ? ? 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: ? > 38

H₁: ? < 38

H₁: ? = 38

H₁: ? ? 38

H₁: ? ? 38
