Answer:
margine of error = 0.13
Step-by-step explanation:
given data
sample proportion = 0.44
simulation trials = 100
sample size = 100
point estimate = 0.44
minimum sample proportion = 0.32
maximum sample proportion = 0.50
solution
we will get here first z score that is express as
............1
here x = 0.32and 0.50
so z will be
so now we get here margin of error that is express as
margin of error = ................2
we use here z heighervalue
margin of error =
margine of error = 0.13
