Answer:of
A Gallup Poll Asked A Random Sample Of 1000 Adults Nationwide The Following Question "Are You In Favor Of The Death Penalty For A Person Convicted Of Murder?" 71% Of The People In The Sample Answered 'Yes' A 99% Confidence Interval
The answer is
At 99% confidence interval, and 71 % of 1000 or 710 success count
The critical z =+/-2.575829
Interval {Min = 0.6730389
Max = 0.7469611}
or Interval {Min = 67.304 %
Max = 74.696 %}
Step-by-step explanation:
Here we utilise the normal distribution to calculate the confidence interval for the data founded on the sample size n and the number of positive pole
= p + z×(p(1-p)/n)
For 99 % z = + or - 2.576
Which give
0.71+ or - 2.576×((0.71×0.29)/1000)^0.5=
0.71+ or -3.69×10^(-2)
Min = 0.67303
Max = 0.74696
Min = 67.304 %
Max = 74.696 %
Which gives expected range in the real population that the statistical result will be found
