Complete the steps needed in solving the z test for proportion of the given statement. For Step 3: z computed, no need to show your solution, answer only, and for Step 4: Decision rule, no need to draw for the graph of the normal curve, just indicate whether the null hypothesis will be rejected or not. 1.) The school registrar estimates that the dropout rate of freshmen high schools in Valernzuela is 20%%. Last year, 90 freshmen from a random sample of 500 Valenzuela freshmen high school Withdrew. At 0.01, is there enough evidence to reject the registrar's claimnm? Solution: Step 1: State the hypotheses. Ho= H1= Step 2: The level of significance and critical region. a = and z certical= Step 3: Compute for the value of one sample z test. Zcomputed= Step 4: Decision rule. Btep 5: Conclusion. 2.) Achaiah made a claimn that at least 5% of the college male students drives racing car. His friend Sofia finds this hard to believe and decided to check the validity of Achaiah's claim, so she took a random sample. At 0.05, does Sofia have sufficient evidence to reject Achaiah's claim if there were 57 racing car in her sample of 750 cars? Solution: Gtep l: State the hypotheses. Ho= H1= &tep 2: The level of significance and critical region. a= and and Zeritical= &tep 3: Compute for the value of one sample z test. Z computed = &tep 4: Decision rule. &tep 5: Conclusion
