From previous studies, it is concluded that 30% of workers were employed from internet resume sites. A researcher claims that the proportion is larger than 30% and decides to survey 300 working adults. Test the researcher's claim at the �=0.01 significance level.

Preliminary:

Is it safe to assume that �≤0.05 of all subjects in the population?
- Yes
- No
Verify ��(1-�)≥10. Round your answer to one decimal place.

��(1-�)=

Test the claim:

The null and alternative hypotheses are
- �0:�≤0.3
  ��:�>0.3
- �0:�≤0.3
  ��:�>0.3
- �0:�=0.3
  ��:�≠0.3
- �0:�≥0.3
  ��:�<0.3
- �0:�≥0.3
  ��:�<0.3
- �0:�=0.3
  ��:�≠0.3
The test is
Based on the sample of 300 people, 36% workers were employed from internet resume sites. What is the test statistic? Round your answer to two decimal places.
What is the �-value? Round your answer to four decimal places.
