Suppose for an upcoming election that a national poll shows that the front runner for the Republican Party has 38% support. The local republicans believes their state is the same as the national poll. To confirm this the local republicans holds their own poll and find that 51 out of 154 support the front-runner. Determine if the hypothesis is correct at alpha= .01. Assume the variable is normally distributed. Determine the test value.

Step 1
Null hypothesis (H0): The proportion of support for the front-runner in the state is the same as the national poll, p = 0.38. Alternative hypothesis (H1): The proportion of support for the front-runner in the state is different from the national poll, p ≠ 0.38. Show more…

A newspaper is conducting a statewide survey concerning the race for governor. The newspaper will take a simple random sample of n registered voters and determine X = the number of voters that will vote for the Democratic candidate. Is there evidence that a clear majority of the population will vote for the Democratic candidate? To answer this, they will test the hypotheses H 0: p = 0.50 versus H a: p > 0.50. If n = 120 and X = 64, what is the P-value for this hypothesis test? less than 0.0002 0.0104 0.0330 0.2326

Two individuals are running for mayor of your town. You conduct an election survey a week before the election and find that $51 \%$ of the respondents prefer candidate A. Can you predict a winner? Use the $99 \%$ level. (HINT: In a two-candidate race, what percentage of the vote would the winner need? Does the confidence interval indicate that candidate $A$ has a sure margin of victory? Remember that while the population parameter is probably $[\alpha=0.01]$ in the confidence interval, it may be anywhere in the interval.) $$ \begin{aligned} &P_{s}=0.51 \\ &N=578 \end{aligned} $$
A random sample of n=1100 registered voters was taken and it was found that 570 would vote for the Republican candidate in a state senate race. Let p represent the proportion of registered voters who would vote for the Republican candidate. Consider testing H0: p = 0.50 Ha: p > 0.50. (a) The test statistic is z = (b). Regardless of what you actually computed, suppose your answer to part (a) was z = 1.28. Using this z, the p-value =
