- Q1
What is referred as an assumption regarding the population parameter that is assumed to be true?

alternative hypothesis

process

null hypothesis

decision

30sM11/12SP-IVa-1 - Q2
Which of the following statement is NOT true on hypothesis testing?

Assumptions should be expressed into two opposing statements.

A second statement is needed to be proven as true.

Alternative statement must be conformed with the null hypothesis.

A null hypothesis is a statement that needs to be tested.

30sM11/12SP-IVa-1 - Q3
A soda factory claims that each bottle of their beverage drink has a volume of 355 ml all the time. A consumer representative inspector claimed that the factory’s beverage drink is not exactly filled at 355 ml. Under which of the following conditions would the inspector commit a Type I error?

He concludes the volume is not 355 ml, when actually it is.

He concludes the volume is not 355 ml, when actually it is not

He concludes the volume is 355 ml, when actually it is.

He concludes the volume is 355 ml, when actually it is not.

A soda factory claims that each bottle of their beverage drink has a volume of 355 ml all the time. A consumer representative inspector claimed that the factory’s beverage drink is not exactly filled at 355 ml. Under which given conditions would the inspector commit a Type II error?

He concludes the volume is not 355 ml, when actually it is.

He concludes the volume is not 355 ml, when actually it is not.

He concludes the volume is 355 ml, when actually it is

He concludes the volume is 355 ml, when actually it is not.

30sM11/12SP-IVa-1 - Q5
Which of the following is utilized as a safeguard not to commit a Type I error?

type II error

acceptance region

rejection region

level of significance

µ

x̅

30sM11/12SP-IVb-1 - Q7
After the evaluation exam, a section of 40 students produced a mean score of 72. She chose 18 students who got the lowest scores for an intervention. The teacher introduced a different strategy on the same lesson and gave a test whose questions are parallel to the first examination. This time the student got a mean score of 73.5. Is there enough evidence to prove that her new strategy improved the performance of her students?

µ ≠ 72

µ < 72

µ > 72

µ = 72

30sM11/12SP-IVb-1 - Q8
If the alternative hypothesis on no. 7 problem will be µ > 72, it means

The intervention is effective

The intervention is not effective

The intervention results just as par with the usual method.

The intervention has a fair result

30sM11/12SP-IVb-1 - Q9
The value derived from the table defined by alpha(a) in which the computed test statistic will be compared in stating the decision rule for hypotheses testing.

computed value

variance

critical value

mean

30sM11/12SP-IVc-1 - Q12
The hypothesis, denoted by H0, is a statement that there is no difference between a parameter and a specific value, or that there is no difference between two parameters

Hypothesis Testing

Null Hypothesis

None of the above

Alternative Hypothesis

30sM11/12SP-IVd-1 - Q13
Given: X = 120,µ = 110, µ= 15, n = 500. State the null and alternative hypotheses at two-tailed test.

H0: µ ≠ 110, Ha: µ≠ 110

H0:µ = 110, Ha: µ < 110

H0: µ = 110, Ha: µ ≠ 110

H0: µ = 110, Ha: µ > 110

30sM11/12SP-IVd-1 - Q14
It is a decision-making process for evaluating whether the null hypothesis should be rejected.

Confidence level

Critical test

Significance level

Statistical test

30sM11/12SP-IVd-1 - Q15
The rejection region refers to the region where the value of the test statistic lies for which we will reject the null hypothesis. This region is also called ____________________.

directional region

critical region

null hypothesis region

nondirectional region
