. A local business school claims that its graduating seniors get
higher-paying jobs than the national average for business school
graduates. Last year’s figures for salaries paid to all business
school graduates on their first job showed a mean of ₱510.00 per
hour. A random sample of 10 graduates from last year’s class of the
local business school showed the following hourly salaries for
their first job: ₱470.00, ₱515.00, ₱560.00, ₱540.00, ₱520.00,
₱485.00, ₱490.00, ₱530.00, ₱535.00, and ₱545.00. You are skeptical
of the business school’s claim and decide to evaluate the salary of
the business school graduates. Use a nondirectional test with α =
.05. a. State the statistical notation of the null and alternative
hypotheses b. Identify the critical region (not the critical region
boundaries; provide the proper notation). c. Compute the sample
statistic (Show how you got the sample statistic). d. Based on the
test’s results, is your skepticism of the business school’s claim
justified? Why or why not?
