Question

A college surveys incoming students every year. An excerpt of one such survey, for Business students only, is available in MyStatLab. For this question, consider these particular incoming students as a random sample of all students entering Business programs in Canadian colleges for this year (for convenience, we will refer to these students simply as "incoming students"). Complete a formal hypothesis test to answer the following questions, if necessary conditions exist.
a. Is there sufficient evidence to conclude that over 25% of incoming students have laptops? Use α = 0.04.
b. Is there sufficient evidence to conclude that 10% of incoming students rent rooms? Use a 4% level of significance.
c. Is there sufficient evidence to conclude that the average mark of incoming students is over 80%? Use α = 0.04.
d. Is there sufficient evidence to conclude that the amount of savings available for education is less than $6,500? Use α = 0.04.
