image text in transcribed
In a random sample of 258 potential voters registered in the state of Maryland, 105 indicated that they planned to vote in the next general election. In an independently chosen, random sample of 248 potential voters registered in Iowa, 105 indicated that they planned to vote in the next general election. Can we conclude, at the 0.05 level of significance, that the proportion D p of all potential voters in Maryland who plan to vote is less than the proportion p, of all potential voters in Iowa who plan to vote? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H1. Ho : 0 X S H :0 (b) Determine the type of test statistic to use. (Choose one) V 0-0 050 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) 0 00 X 5 (d) Find the p-value. (Round to three or more decimal places.) 0 (e) Can we conclude that the proportion of voters in Maryland who plan to vote is less than the proportion of voters in Iowa who plan to vote? Yes No
