Question

Use the given confidence interval limits to find the point estimate ModifyingAbove p with caret and the margin of error E. 0.556 less than p less than 0.598 ModifyingAbove p with caretequals nothing Eequals nothing ​(Type an integer or a​ decimal.)

Answer 1

Answer:

Given,

Lower confidence interval = 0.556

Upper confidence interval = 0.598

Now let us consider,

Point estimate = (Lower confidence interval + Upper confidence interval )/2

substitute the given values

= ( 0.556 + 0.598 )/2

= 1.154 / 2

= 0.577

Margin of error E = Upper confidence interval -

substitute the known values in above formula

= 0.598 - 0.577

= 0.021

Margin of error = 0.021
