, H0:p = 0.80

Ha:p ≠ 0.80

Find the test statistic for this hypothesis test for a proportion and round your answer to 2
decimal places.

Well done! You got it right.


3.32The proportion of successes is p̂ =221250=0.884.

The test statistic is calculated as follows:

z=p̂ −p0p0⋅ (1−p0)n√

z=0.884−0.800.80⋅ (1−0.80)250√

z≈3.32
Compute the value of the test statistic (z-value) for a hypothesis test for proportion

Question
A researcher is investigating a government claim that the unemployment rate is less than 5%.
To test this claim, a random sample of 1500 people is taken and its determined that 92 people
are unemployed.

The following is the setup for this hypothesis test:

{H0:p=0.05Ha:p<0.05

Find the test statistic for this hypothesis test for a proportion. Round your answer to 2 decimal
places.

Test_Statistic=2.01Great work! That's correct.
