Question
From previous studies, it is concluded that 50% of workers indicate that they are satisfied with their job. A
researcher claims that the proportion is significantly different than 50% and decides to survey 100 working
adults. Test the researcher's claim at the a = 0.02 significance level.
Preliminary:
a. Is ít safe to assume that n <0.05 of all subjects in the population?
Yes
No
b. Verify np(1 - p) > 10. Round your answer to one decimal plaçe.
np(1 – p) = |800
Enter an integer or decimal number (more.
Test the claim:
a. The null and alternative hypotheses are
O Ho:µ > 0.5
Ha:u < 0.5
O Ho:p 2 0.5
Ha:p < 0.5
O Ho:p = 0.5
Ha:p+0.5
Ho:u < 0.5
Ha:u > 0.5
O Ho:p < 0.5
H:p > 0.5
Ho:µ = 0.5
Ha:u + 0.5
b. The test is
two-tailed
c. Based on the sample of 100 people, 42% workers indicate that they are satisfied with their job. What
is the test statistic? Round your answer to two decimal places.
2= v
d. What is the p-value? Round your answer to four decimal places.
e. Make a decision.
