Hypothesis Testing Concepts

At the Chrysler manufacturing plant, there is a part that is supposed to weigh precisely 19 pounds. The engineers take a sample of parts and want to know if they meet the weight specifications. What are our null and alternative hypotheses?

• H_o : μ = 17

  H₁ : μ ≠ 19

• H_o : μ = 19

  H₁ : μ ≠ 19

• H_o : μ = 19

  H₁ : μ ≠ 17

• H_o : μ = 17

  H₁ : μ ≠ 17

Which of the following shows a right-tailed test?

• Ha: µ < 15
• H₀: µ < 15
• Ha: µ > 15
• H₀: µ > 15

H₀: μ = k

H_a: μ ≠ k

• Left-tailed test

• Two-tailed test

• Right-tailed test

miles. Which of the following is the claim?

The principal of the school thinks that average weight of a backpack is not 18.4 lbs. What is the null and alternate hypothesis? 

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

The mean height of women is greater than 64"

• H₀: μ > 64"

• H₀: p > 64"

  Hₐ: p ≠ 64"

• H₀: p = 64"

  Hₐ: p > 64"
