iQ15

Suppose the following hypotheses are to be tested.

?H0 : ? = 150 ?and ?H1 : ? ? 150

A sample of size 15 was collected. According to the flowcharts presented in M140, which hypothesis test should be used?

(You may assume that any additional requirements for your selected test, such as normality and/or equal population variances are satisfied.)

Select one:

A) Matched-pairs t-test

B) Two-sample z-test

C) ?

Solution

Suppose the following hypotheses are to be tested.

?H0 : ? = 150 ?and ?H1 : ? ? 150

for a population in which the population variance is known and has the value .

A sample of size 15 was collected. According to the flowcharts presented in M140, which hypothesis test should be used?

(You may assume that any additional requirements for your selected test, such as normality and/or equal population variances are satisfied.)

This is single sample test comparing sample mean with population mean.

The population is normal and population variance is known.

This is single sample z test.

Answer F

Select one:

A) Matched-pairs t-test

B) Two-sample z-test

C) ?
