• left tailed

• two tailed

• not enough information

The test is

• let tailed

• right tailed

• two tailed

• not enough information

You are performing a right-tailed test with test statistic z=1.249, find the p-value accurate to 4 decimal places.

(a)  

You are conducting a study to see if the probbility of catching the flue is significantly more than 0.84. Thus you are performing a right tailed test for a population proprotion. Your sample data produce the test statistic z=2.718. Find the p-value accurate to 4 decimal places.

(a)  

When we are coducting a two-tailed hypothesis test for a proportion, if the test statistic z=1.49, what is the P-value? (Round your answer to 3 decimal places.)

(a)  

Given the claim that the population mean is greater than 32.4, we can construct the following two hypotheses:

Label these hypotheses as the null or alternative.

a) Which of the following hypotheses is the null hypothesis?

• μ≤32.4

• μ=32.4

• μ≥32.4

• μ>32.4

Given the claim that the population mean is greater than 32.4, we can construct the following two hypotheses:

Which of the following hypotheses is the alternative hypothesis?

• μ<32.4

• μ=32.4

• μ>32.4

• μ≠32.4

You are conducting a study to see if the probability of catching the flu this year is significantly more than 0.15. Thus you are performing a right-tailed test for a population proportion. Your sample data produce the test statistic z=2.429. Find the p-value accurate to 4 decimal places.
