Quiz in Hypothesis Testing

It is a proposed explanation, assertion, or assumption about a population parameter or about the distribution of a random variable.

• Decision

• Statistics

• Probability

• Hypothesis

It is also the probability of making the wrong decision when the null hypothesis is true.

• Level of error

• Level of hypothesis

• Level of acceptance

• Level of significance

In a one-tailed test, in which critical value listed below will the computed t of 2.313 fall in the acceptance region?

• 1.383

• 1.533 

• 2.228

• 2.365

Which of the following describes an alternative hypothesis in a left tailed test? 

• 𝐻𝑎 <100

• 𝐻𝑎 =100

• 𝐻𝑎 ≥100

• 𝐻𝑎 ≤100

Using a left-tailed test, which of the following value of z falls in the rejection region where the critical value is – 1.725?

• – 1.700

• – 1.715

• – 1.724

• – 1.728

(a)   is basically testing an assumption that we make about a population.

The level of significance is denoted by (a)   .

When the alternative hypothesis is two-sided, it is called (a)   .

When the given statistics hypothesis assumes a less than or greater than value, it is called (a)   .

The                          region is the set of all values of the test statistic that causes us to reject the null hypothesis.
