Na poll, 51% of the people polled answered yes to the question "are you in favor of the death penalty for a person convicted of murder? " the margin of error in the poll was 3%, and the estimate was made with 95% confidence. at least how many people were surveyed? the minimum number of surveyed people was nothing. (ro

1067

Step-by-step explanation:

Given : The proportion of  people polled answered yes to the question = P= 0.51

Margin of error :E= 0.03

Confidence interval = 95%

Z-score for 95% confidence interval (from z-value table )z*=1.960

Formula to find the sample size is given  by :-

Substitute the value of p and E  then, we have

Hence, The minimum number of surveyed people was 1067.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
