5. An educator is testing the null hypothesis that the percentage of 14-16-year-olds who are happy
about returning to school in September is less than or equal to 50%. The educator conducts a poll
of 1200 randomly selected 14-16-year-olds and finds that 630 teens are happy about returning to
school in September. Based on this poll, the educator should make which of these conclusions (at
the 5% level of significance)?
A. There is evidence that the true percentage is greater than 50% because the P-value is less
than 0.05.
B. There is evidence that the true percentage is greater than 50% because the P-value is greater
than 0.05.
C. There is no evidence that the true percentage is greater than 50% because the P-value is less
than 0.05.
D. There is no evidence that the true percentage is greater than 50% because the P-value is
greater than 0.05.
E. You can't compute a P-value with a null hypothesis of this form.
