In a survey of 210 males ages 20 to 24, 38% were neither in school nor working. In a survey of 220 females ages 20 to 24, 45% were neither in school nor working. These samples are random and independent. At α=0.06, can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school nor working? Complete parts (a) through (e) below. (a) Identify the claim and state H0 and Ha. (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is(are) nothing. (Use a comma to separate answers as needed. Round to two decimal places as needed.) Identify the rejection region(s). Choose the correct answer below. (c) Find the standardized test statistic. z= (Round to two decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.
