he engineering school at a major university claims that less than 65% of its graduates are men. A random sample of 600 recent graduates from the engineering found that 369 were men. Is there sufficient evidence to conclude the school’s claim is correct at α = 0.04? (a) Write the null and alternative hypotheses. (b) Find the test statistic, z0. _________________ (write the answer as a decimal rounded to 4 decimal places). (c) Find the P-value. _________________ (write the answer as a decimal rounded to 4 decimal places). (d) State the conclusion, including reasoning through comparison of the P-value to α.
