Question

Suppose a researcher claims that µ, the average magnitude of all earthquakes (as measured on the Richter scale), is greater than 1.00. Express in symbolic form the null and alternative hypotheses needed to test the researcher's claim.

H₀ : µ ≥ 1.00
H_A : µ < 1.00

H₀ : µ ≠ 1.00
H_A : µ = 1.00

H₀ : µ = 1.00
H_A : µ ≠ 1.00

H₀ : µ = 1.00
H_A : µ > 1.00

Answer 1

solution

this is the right tailed test .  

The null and alternative hypothesis is ,

H0 :   = 1.00

HA : >1.00
