A poll found that in a random sample of 1000 American adults, 710 indicated that they oppose the reinstatement of a military draft. Is there convincing evidence that the proportion of American adults who oppose reinstatement of the draft is greater than 0.7? Use a significance level of 0.05. (Round your test statistic to two decimal places and your P-value to four decimal places.)

-Accept

-There is no sufficient evidence to back the claim that the proportion of American adults who oppose reinstatement of the draft is greater than 0.7

Step-by-step explanation:

-We state our hypotheses as:

#We the calculate the proportion to be studied using the formula:

-The z-value from this proportion is calculated as follows:

#We compare this z-value to the z-value at 95% confidence level:

Hence, Accept the null hypothesis.

-There is no sufficient evidence to back the claim that the proportion of American adults who oppose reinstatement of the draft is greater than 0.7

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
