Hypothesis Testing

1. 1. A hypothesis that is contrary to the null hypothesis.

• Altered Hypothesis

• Alternating Hypothesis

• Alternative Hypothesis

• Active Hypothesis

1. 2. Null Hypothesis is denoted by

• N_H

• H_N

• H_A

• H_O

3. Is a prediction regarding the possible outcomes of a study.

• Statistical Hypothesis

• Clinical Hypothesis

• Statement Hypothesis

• Predictive Hypothesis

4. A Hypothesis that uses a relationship symbol such as ≥, ≤, and =

• Alternative Hypothesis

• Alternating Hypothesis

• Nall Hypothesis

• Null Hypothesis

5. A Hypothesis that uses keywords such as "not equal, different from, not the same, greater than, above, increased, less than, below, reduced from"

• Alternative Hypothesis

• Alternating Hypothesis

• Nall Hypothesis

• Null Hypothesis

6. What is the "key word/phrase" in the claim

"The average monthly income of Filipino families who belong to low-income is 8, 000"

• average

• low-income

• is

• 8, 000

7. Which of the following is an example of a null hypothesis?

• μ₁ ≠ μ₂

• The average life expectancy of females is not the same of males.

• μ₁ > μ₂

• μ₁ = μ₂

8. "A teacher wants to test the claim that μ₁ female students have fewer absences compared to μ₂ male students."

State the alternative hypotheses.

• μ₁ ≥ μ₂

• μ₁ = μ₂

• The mean number of absences of female students is greater than or equal of male students.

• The mean number of absences of female students is less than of male students.

9. "A teacher wants to test the claim that μ₁ female students have greater absences compared to μ₂ male students."

State null hypotheses.

• μ₁ ≥ μ₂

• μ₁ = μ₂

• The mean number of absences of female students is less than or equal of male students.

• The mean number of absences of female students is less than of male students.

10. "A teacher wants to know if there is a significant difference between the mean score in the Statistics test of students in his morning and afternoon classes."

Identify the type of hypothesis testing that will be used.

• Two-Tailed Test

• One-Tailed Test

• Right-Tailed Test

• Left-Tailed Test
