Question

From previous studies, it is concluded that 45% of workers got their job through college. A researcher claims it has decreased and decides to survey 100 adults. Test the researcher's claim at the �=0.05 significance level.

Verify ��^(1-�^)≥10. Round your answer to one decimal place.

��^(1-�^)=

Test the claim:

Express the null and alternative hypotheses in symbolic form for this claim.

�0:
��:
After surveying 100 adult Americans, the researcher finds that 63 workers got their job through college. Compute the test statistic. Round to two decimal places.

�=
What is the �-value? Round to 4 decimals.

�=
Make a decision based on �=0.05 significance level.
- Reject the null hypothesis.
