Of 300 female registered voters surveyed, 145 indicated they were planning to vote for the incumbent senator; while of 400 male registered voters, 125 indicated they were planning to vote for the incumbent senator. We want to investigate if the proportion of males favoring the incumbent is lower than the females. A) state the null and alternative hypothesis for a = 0.01. State the rejection criteria using the critical value method. B) Compute the P-value? Please solve without MS Excel

Step 1
The alternative hypothesis (H1) is that the proportion of males favoring the incumbent senator is lower than the proportion of females favoring the incumbent senator. H0: p_male = p_female H1: p_male < p_female Show more…

It is said that more males register to vote in a national election than females. A research organization selected a random sample of 300 registered voters and reported that 165 of the registered voters were male. a. Formulate the hypotheses for this problem. b. Compute the standard error of . c. Compute the test statistic. d. Using the p-value approach, can you conclude that more males registered to vote than females? Let α = .05. Please show all workings clearly.

Given the sample data below, test the claim that the proportion of male voters who plan to vote Republican at the next presidential election is greater than the percentage of female voters who plan to vote Republican. State the Null and Alternative hypotheses. Use the P-value method of hypothesis testing and use a significance level of 0.10. Men: n1 = 250, x1 = 146 Women: n2 = 202, x2 = 103

Perform these steps. a. State the hypotheses and identify the claim. b. Find the critical value(s). c. Compute the test value. d. Make the decision. e. Summarize the results. Use the traditional method of hypothesis testing unless otherwise specified. A study is conducted to determine if the percent of women who receive financial aid in undergraduate school is different from the percent of men who receive financial aid in undergraduate school. A random sample of undergraduates revealed these results. At $\alpha=0.01,$ is there significant evidence to reject the null hypothesis? $$ \begin{array}{lcc} & \text { Women } & \text { Men } \\ \hline \text { Sample size } & 250 & 300 \\ \text { Number receiving aid } & 200 & 180 \end{array} $$
