Hypothesis Test #2

Which of the following represents the appropriate null & alternative hypotheses?

The mean height of women is greater than 64"

• H₀: μ > 64"

  Hₐ: μ ≠ 64"

• H₀: μ < 64"

  Hₐ: μ > 64"

• H₀: p > 64"

  Hₐ: p ≠ 64"

• H₀: p = 64"

  Hₐ: p > 64"

Which of the following is not an option for an alternate hypothesis? 

• H_a = k
• H_a > k
• H_a < k
• H_a ≠ k

You do not need BOTH null and alternate hypotheses when testing

• True

• False

A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm. What is the null hypothesis?

• H₀: μ = 174.1 cm

• H₀: μ < 174.1 cm

• Hₐ: μ = 174.1 cm

• Hₐ: μ  $\ne$   174.1 cm

A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm. What is the alternative hypothesis?

• H₀: μ = 174.1 cm

• H₀: μ  $\ne$  174.1 cm

• Hₐ: μ = 174.1 cm

• Hₐ: μ  $\ne$   174.1 cm

When p-value is greater than alpha we:

• Reject Ho

• Fail to reject Ha

• Fail to reject Ho

• Reject Ha

In performing a hypothesis test where the claim is that the μ = 6.9. A random sample of 16 items is selected. The sample mean is 7.1 and the sample standard deviation is 2.4. It can be assumed that the population is normally distributed at α = .05.

• Reject Ho

• Reject Ha

• Fail to reject Ho

• Fail to reject Ha
