Question

The statement represents a claim. Write its complement and state which is H0 and which is H1. μ = 9.3

A) H0: μ ≠ 9.3 ; H1: μ = 9.3 (claim)
B) H0: μ = 9.3 (claim); H1: μ ≠ 9.3
C) H0: μ ≥ 9.3 (claim); H1: μ < 9.3
D) H0: μ ≤ 9.3 ; H1: μ > 9.3

Answer 1

B

Answer 2

Answer: B)
`H_0:\mu=9.3`

`H_1:\mu\\eq9.3`

Explanation:

The given claim :
`\mu=9.3` which contains equals to sign.

The complement of the "equal" sign is "not equal to" sign.

So the complement of the above statement will be :-

`\mu\\eq9.3`

Since we know that the null hypothesis always contains the equals signa , so the null hypothesis for the given claim will be:_

`H_0:\mu=9.3`

Also, the alternative hypothesis is complement of null hypothesis , so the alternative hypothesis for the given claim:-

`H_1:\mu\\eq9.3`
