Use the sample data and confidence level given below to complete parts a through d.
a research institute poll asked respondents if they felt vulnerable to identity theft. in the poll, n=1096 and x=542 who said yes. use a 95% confidecne level.
a. find the best point of estimate of the population of portion p.
b. identify the value of the margin of error e.
e= round to four decimal places as needed.
c. construct the confidence interval.
_ < p < _ round to three decimal places.
d. write a statement that correctly interprets the confidence interval.

Step-by-step explanation:

Given that a research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=1096 and x=542 who said yes.

i.e. sample size =

who said yes =

Sample proportion =

Std error of proportion =

Margin of error 95%

Hence confidence interval for proportions

=

a) Point estimate

B) Margin of error =

C) Conf interval =

D) We are 95% confident that for large random samples representing the population, the proportion of yes will lie between these two values.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
