hypothesis testing

1.    What is the sample proportion if 58 out of 250 respondents agreed on a certain claim?

• 0.21 

• 0.23

• 0.22

• 0.24

the third step in solving the z critical value method?

• compute for the test statistics

• determine the null hypothesis

• determine the alternative hypothesis

• draw a conclusion

A local poll claims that the barangay captain of a certain barrio has less than a 50% positive approval rating. Out of 120 respondents, 75 have a positive response towards the performance of their barangay captain.

2. 2.    How will you write the null hypothesis in symbols?

• p ≤ 0.50

• p ≥ 0.50

• p ≠ 0.50

• p = 0.50

A local poll claims that the barangay captain of a certain barrio has less than a 50% positive approval rating. Out of 120 respondents, 75 have a positive response towards the performance of their barangay captain.

3. 3.    How will you write the alternative hypothesis in symbols?

• p < 0.50

• p > 0.50

• p ≠ 0.50

• p = 0.50

A local poll claims that the barangay captain of a certain barrio has less than a 50% positive approval rating. Out of 120 respondents, 75 have a positive response towards the performance of their barangay captain.

5.    What is its p-value?

• 0.0022

• 0.4978

• 0.0044

• 0.5000

• A local poll claims that the barangay captain of a certain barrio has less than a 50% positive approval rating. Out of 120 respondents, 75 have a positive response towards the performance of their barangay captain.

• -   If we do the z-test, what will be the computed z?

• 2.84 

• 2.85 

• 2.86

• 2.87

      H_o: 𝑝 = 0.35            H_a: 𝑝 ≠ 0.35     

     𝑝̂ = 0.45,       n = 55     , 𝛼= 0.01

-what is the null and alternative hypothesis?

 

• Ho: 𝑝 = 0.35 

  H_a: 𝑝 ≠ 0.35 

•  Ho: 𝑝<0.35 

  H_a: 𝑝 ≠ 0.35 

• Ho: 𝑝 = 0.35 

  H_a: 𝑝 > 0.35 

• Ho: 𝑝 > 0.35 

  H_a: 𝑝 ≠ 0.35 

     H_o: 𝑝 = 0.35            H_a: 𝑝 ≠ 0.35     

     𝑝̂ = 0.45,       n = 55     , 𝛼= 0.01

 -What is the level of significance?

• 0.01

• 0.05

• 0.02

• 0.75

what is the third step in solving the critical value method?

• compute for the test statistics

• draw a conclusion

• determine the null hypothesis

• determine a alternative hypothesis

fourth step that you need to get in solving the critical value method?
