Answer 1

Given that 200 Samble size (m) number of favorable Cases (x) = 120 Sample Proportion (@) 120 =0.60 200 = 0.60 level of significance (2) = 0.05 Null hybothesis ( HO) : 0.5 P-0.5 Alternative hypothesis (HO) This Corresponds to a for which z. test for needs to be right. tailed test Population Prokoston one used, Test statistic : The test statistic is given by р-Р Z r!
