Question

Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming
election? Of the 312 randomly selected registered voters surveyed, 62 of them will vote in the upcoming
election. What can be concluded at the a = 0.05 level of significance?
%3D
a. For this study, we should use
Select an answer
b. The null and alternative hypotheses would be:
Ho:
Select an answer
(please enter a decimal)
Select an answer
(Please enter a decimal)
c. The test statistic ? 0
(please show your answer to 3 decimal places.)
%3D
d. The p-value
(Please show your answer to 4 decimal places.)
%3D
e. The p-value is ? a
f. Based on this, we should Select an answer O the null hypothesis.
g. Thus, the final conclusion is that
O The data suggest the populaton proportion is significantly higher than 19% at a = 0.05, so there is
statistically significant evidence to conclude that the the percentage of all registered voters who
will vote in the upcoming election will be higher than 19%.
The data suggest the population proportion is not significantly higher than 19% at a = 0.05, so
there is statistically significant evidence to conclude that the percentage of registered voters who
will vote in the upcoming election will be equal to 19%.
The data suggest the population proportion is not significantly higher than 19% at a = 0.05, so
there is statistically insignificant evidence to conclude that the percentage of registered voters
who will vote in the upcoming election will be higher than 19%.

The recommended dietary allowance (RDA) of vitamin C for women is 75 milligrams (mg) per day. A hypothesis test, with a significance level of 0.05, is to be performed to decide whether adult women are, on average, getting less than the RDA of 75 mg per day. A researcher gathers data from a random sample of women in order to carry out the test. Determine the Null and Alternative hypotheses.
Recently, a large academic medical center determined that 7 of 15 employees in a particular position were male,whereas 56% of the employees for this position in the general workforce were male. At the 0.01 level of significance, is there evidence that the proportion of males in this position at this medical center is different from what would be expected in the general workforce? What are the correct hypotheses to test to determine if the proportion is different? A. H0:π≥0.56; H1:π<0.56 B. H0:π=0.56; H1:π≠0.56 C.H0:π≤0.56; H1:π>0.56 D.H0:π≠0.56; H1:π=0.56 Part 2 Calculate the test statistic. ZSTAT=enter your response here (Type an integer or a decimal.

At a significance level of 0.05, and using two-tailed test: a.) What should be the good hypotheses? b.) What is the t-value/z-value? c.) Is there is a difference between the two states?
If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.6792 and ZSTAT=−0.47,what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? Since the p-value is Less than or Greater than or equal to a= , Reject , Do not reject H0.
According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.
In a survey taken in 2020, 20 out of 50 women and 17 out of 45 men said that they felt our country was headed in the wrong direction regarding universal health care. Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel out country is headed in the wrong direction regarding healthcare are equal? Use the P-Value Method of Testing. In your work space below, you will need to have -1. The null hypothesis, Ho 2. The alternative hypothesis, H1 3. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho

The National Institute of Mental Health published an article stating that in any one-year period, approximately 8.8% of American adults suffer from depression or a depressive illness. Suppose that in a survey of 2000 people in a certain city, 11.3% of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that city suffering from depression or a depressive illness is more than the 8.8% in the general adult American population. Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4 decimal places. a. What are the correct hypotheses?
