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 Valenzuela 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 claim? Solution: Step 7: State the hypotheses. Ho: HI: Step 2: The level of significance and critical region. a = and Zcritical= Step 3: Compute for the value of one sample z test. Zcomputed= Step 4: Decision rule. Step 5: Conclusion
