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
