Question

Political Science: Voters This problem is based on information taken from The Rating Guide to Life in America’s Fifty States, by G.S. Thomas. A random sample of n1= 288 voters registered in the state of California showed that 141 voted in the last general election. A random sample of n2= 216 registered voters in the state of Colorado showed that 125 voted in the most recent general election. Do these data indicate that the population proportion of voter turnout in Colorado is higher than that in California? Use a 5% level of significance.

- What is the level of significance? State the null and alternate hypotheses.
- Check Requirements What sampling distribution will you see? What assumptions are you making? Compute the sample test statistic.
- Find (or estimate) the P-Value. Sketch the sampling distribution and show the area corresponding to the P-Value.
- Based on your answers in parts (a)-(c), will you reject or fail
to reject the null hypothesis? Are the data statistically
significant at level
*a?* - Interpret your conclusion in the context of the application.

Political Science: Voters This problem is based on information
taken from The Rating Guide to Life in America’s Fifty States, by
G.S. Thomas. A random sample of n1= 288 voters registered in the
state of California showed that 141 voted in the last general
election. A random sample of n2= 216 registered voters in the state
of Colorado showed that 125 voted in the most recent general
election. Do these data indicate that the population proportion of
voter turnout in...

A random sample of n1 = 288 voters registered in the state of
California showed that 147 voted in the last general election. A
random sample of n2 = 217 registered voters in the state of
Colorado showed that 130 voted in the most recent general election.
Do these data indicate that the population proportion of voter
turnout in Colorado is higher than that in California? Use a 5%
level of significance.
What is the test statistic?
Find the P-Value

A random sample of n1 = 289 voters registered in the state of
California showed that 141 voted in the last general election. A
random sample of n2 = 212 registered voters in the state of
Colorado showed that 128 voted in the most recent general election.
Do these data indicate that the population proportion of voter
turnout in Colorado is higher than that in California? Use a 10%
level of significance. (a) What is the level of significance?

Minnesota had the highest turnout rate of any state for the 2016
presidential election.† Political analysts wonder if turnout in
rural Minnesota was higher than turnout in the urban areas of the
state. A sample shows that 630 of 840 registered voters from rural
Minnesota voted in the 2016 presidential election, while 396 out of
550registered voters from urban Minnesota voted.
(a)
Formulate the null and alternative hypotheses that can be used
to test whether registered voters in rural Minnesota...
