A student wishes to see if at her work place the proportion females who do not have children is less than the proportion of males who do not have children. To test her claim she randomly selects 358 females 60 did not have children. She then randomly selects 322 males workers and out of them 59 did not have children. Test her claim at œ=0.05 to see if she was right. The correct hypotheses are: О Но: рr рм(claim) Ο H: pF PM НА: PF < рм (claim) O Ho:PF На: рr + рм (claim) = PM Since the level of significance is 0.10 the critical value is -1.282 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho
