05-02: Hypothesis Testing Evaluation Quizizz

In testing hypotheses, which of the following would be strong evidence against the null hypothesis?

• using a small level of significance
• using a large level of significance
• obtaining data with a small p-value
• obtaining data with a low test statistic

Suppose the P-value for a hypothesis test is 0.0304. Using a = 0.05, what is the appropriate conclusion?

• a) Reject the null hypothesis

• b) Reject the alternative hypothesis

• c) Fail to reject the null hypothesis

• d) Fail to reject the alternative hypothesis

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

The mean height of women is greater than 65"

• H₀: μ > 65"

  Hₐ: μ ≠ 65"

• H₀: μ < 65"

  Hₐ: μ > 65"

• H₀: p > 65"

  Hₐ: p ≠ 65"

• H₀: p = 65"

  Hₐ: p > 65"

Of the following, which is the only appropriate option for the null hypothesis? 

• H₀: p = k

• H₀: μ > k

• H₀: μ < k

• H₀: p ≠ k

Of the following, which is not an appropriate option for an alternate hypothesis? 

• H_a: μ = k

• H_a: μ > k

• H_a: p < k

• H_a: μ ≠ k

The weight of the average 6th grade student's backpack (with books in it) is 18.4 lbs. The principal of the school thinks that the backpack does not weight 18.4 lbs. What is the null and alternate hypothesis? 

• H₀: μ = 18.4

  H_a: μ = 18.4

• H₀: μ = 18.4

  H_a: μ > 18.4

• H₀: μ = 18.4

  H_a: μ < 18.4

• H₀: μ = 18.4

  H_a: μ ≠ 18.4

A level of significance of 5% means:

• There's a 5% chance we're wrong
• There's a 5% chance we'll be wrong if we fail to reject the null hypothesis
• There's a 5% chance we'll be wrong if we reject the null hypothesis.
• There's a 5% chance you'll get an A on the test.

It is the center of the normal curve.

• mean

• standard deviation

• variance

• proportion
