In a sample of 808 Republicans, 380 answered that they believethat Sarah Palin has the right experience to be President. Assumingthe polling was done correctly and that the data is current, is itreasonable to conclude at a significance level of .01 that lessthan fifty percent of Republicans feel that Sarah Palin has theright experience to be President?
State the following:
1. sample size
2. sample proportion to three decimal places
3. what type of variable is it?
4. The data is collected from an SRS. Is the sample sizesufficiently large?
5. state the null hypothesis.
6. state the alternate hypothesis.
7. write the formula for the standard error and compute it tofour decimal places.
8. write the formula for the z-value (test statistic) andcompute it to two decimal places.
9. critical value(s)
10. p-value table A3
11. p-value table A2
12. p-value calculator
13. can we reject?
14. conclusion
15. (same problem as above but the level of significance is .05instead of .01) critical value (s)
15b. conclusion with .05 level
