On the basis of a survey of 545 television viewers, a statistician has constructed a confidence interval and estimated that the
Tju [1.3M]

Answer:

0.98 also 98%

Step-by-step explanation:

In this question we have the Lower limit to be 0.16

We have the Upper limit to be 0.24

Such that (0.16+0.24)/2 = 0.40/2 = 0.20

Standard deviation= √(0.2x0.8/545) this gives 0.017134

Next we get margin of error

Margin of error = 0.24-0.20 = 0.04

Z multiplied by sd =0.04

Such that

Z = 0.04/0.017134 =2.33

On this z score, the Corresponding level of confidence is 0.98

Which is 98%

Sliva [168]
Anytime you have text problem you need to write equation just read text bit by bit and write equation as you are reading text!

It starts with "the sum" which means we are using + to sum some numbers.
Next is "three". which means we are summing some 3 numbers.
Next is" consecutive even integers" for that you need to know if 4 is one number than next consecutive even number is 6 or 4+2.
And all is equal to 36.
which means we write:
x + (x+2) + (x+4) = 36  where x is least of those numbers.

3x + 6 = 36
3x = 30
x = 10.

Least consecutive even integer in this task is 10.
