Applying What You’ve Learned Use the following table of student information to determine whether the statements in Exercises 35 − 40 are true or false. If a statement is false, explain why it is false using rules of quantifiers that we have developed. For example, the statement “All sophomores are on scholarship” is false because “There exists a sophomore (Stephen) who is not on scholarship.” Name Year Scholarship Athlete Commuter Lennox Freshman Yes Yes No Marilu Freshman No No Yes Stephen Sophomore No Yes Yes Omarosa Junior Yes No No Tito Sophomore Yes Yes Yes Nadia Sophomore Yes Yes No Piers Junior Yes No Yes No athletes are commuters.

You want to determine whether or not the mean of the population from which this sample was taken is significantly different from 49. (Assume the population is normally distributed.)
(a)
State the null and the alternative hypotheses. (Enter != for ≠ as needed.)
H0:
Ha:
(b)
Determine the test statistic. (Round your answer to three decimal places.)
(c)
Determine the p-value, and at the 5% level of significance, test to determine whether or not the mean of the population is significantly different from 49.
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
Reject H0. There is insufficient evidence to conclude that the mean of the population is different from 49.Do not reject H0. There is sufficient evidence to conclude that the…
