Intro to hypothesis testing

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

The mean height of women is greater than 64"

• H₀: μ > 64"

  H₁: μ ≠ 64"

• H₀: p = 64"

  H₁: p > 64"

Which of the following shows a right-tailed test?

• H₁: µ < 15

• H₀: µ < 15

• H₁: µ > 15

• H₀: µ > 15

What is the only option for a null hypothesis? 

• H₀ = k

• H₀ > k

• H₀ < k

• H₀ ≠ k

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

• H₁ = k

• H₁ > k

• H₁ < k

• H₁ ≠ k

A car manufacturer advertises that its new subcompact models get 47 mpg. If μ is the mileage of these cars, what could be the null and alternate hypothesis if we wanted to check if the car's mpg is overrated? (meaning it would get less)

• H₀: μ = 47

  H₁: μ = 47

• H₀: μ = 47

  H₁: μ ≠ 47

In a hypothesis test, the alternative hypothesis is always a statement of equality. 

• True
• False
