Is there enough evidence to support the researcher's suspicion that the proportion of myopia cases in 2018 is higher than the proportion of myopia cases in 20007 Use alpha = 0.05. Let P1 represent the proportion of myopia cases in 2018 and let p2 be the proportion of myopia cases in 2000. 1) State Ho and Ha 2) Calculate the value of the test statistic, z (round to 2 decimal places) 3) Calculate the p-value (round to 4 decimal places) 4) Decide to reject or fail to reject Ho 5) Write your conclusion in the context of the claim. When stating the hypotheses, for less than sign, use , for equal use = and for not equal, use =/ B USI X , x Insert Formula
