An exit poll of 1000 randomly selected voters found that 515 favored measure a. a. construct a 99% confidence interval for the support of measure a. b. suppose measure a needs at least 50% support to pass, what are the null and alternative hypotheses if we were to test to see if measure a will pass? c. compute the p-value of the above test.

Step-by-step explanation:

Given that an  exit poll of 1000 randomly selected voters found that 515 favored measure A.

Sample proportion p =

Margin of error 99% = 2.58*SE

=

99% confidence interval =

------------------------

(Right tailed test)

STd error =

Test statistic Z = p diff/std error =

p value = 0.1714

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.
