Question 918668: As a part of its marketing strategy at a tertiary institution, the brochure
states that 62% of the students get a job immediately out of college.
Given the current labour market, you believe that this claim is dubious
and the rate should be lower. Of the 100 persons surveyed, 55 got a
job immediately. Is the claim supported at the 5% significance level?

Ho: p = .62 (claim)
Ha: p < .62
........
z = %28.55-.62%29%2Fsqrt%28.62%2A.38%2F%28100%29%29 = -.07/.0485 = -1.4421
5% significance level, critical value = -1.645 (One-tailed)
-1.442 > -1.645,accept claim
