Only 14% of registered voters voted in the last election. Will voter participation decline for the upcomingelection? Of the 373 randomly selected registered voters surveyed, 37 of them will vote in the upcomingelection. What can be concluded at the a = 0.01 level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ? v Select an answer V(please enter a decimal)H1:? V Select an answer V(Please enter a decimal)c. The test statistic ? V =(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is ? v af. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the populaton proportion is significantly lower than 14% at a = 0.01, so thereis statistically significant evidence to conclude that the the percentage of all registered voterswho will vote in the upcoming election will be lower than 14%.O The data suggest the population proportion is not significantly lower than 14% at a = 0.01, sothere is statistically significant evidence to conclude that the percentage of registered voterswho will vote in the upcoming election will be equal to 14%.The data suggest the population proportion is not significantly lower than 14% at a = 0.01, sothere is statistically insignificant evidence to conclude that the percentage of registered voterswho will vote in the upcoming election will be lower than 14%.

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 32 of the 39 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 81 of the 94 subjects developed rhinovirus infections. Use a 0.05 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. b. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is< (P, - P2) < (Round to three decimal places as needed.)
Use the five steps in hypothesis testing. 1. Agriculture: Ground Water Unfortunately, arsenic occurs naturally in some ground water (Reference: UnionCarbide Technical Report K/UR-1. A mean arsenic level of parts per billion (ppb) is considered safe foragricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. Arandom sample of 37 tests gave a sample mean x̄ = 7.2 ppb arsenic, with s= 1.9 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb? Use a= 0.01

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
