Considering the margin of error of a confidence interval, it is found that the correct option is:

It would be half as wide.

<h3>What is the margin of error of a confidence interval?</h3>

It is modeled by:

M = z\frac{s}{\sqrt{n}}

In which:

  • z is the critical value.
  • s is the standard deviation.
  • n is the sample size.

From this, we get that the margin of error is inversely proportional to the square root of the sample size. Then, multiplying the sample size by 4, when it changes from 50 to 200, cuts the margin of error in half, making the interval half as wide.

Jim thinks of a number (n). He adds 5 to the
Karolina [17]

Answers + Step-by-step explanation :

a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign

b) we can solve our equation to find for n, the number jim thought of

7(n + 5) = 91
I will use the distributive property.

7n + 35 = 91

Subtract 35 on both sides

7n = 56

Now divide 7 on both sides to find n

n = 8

The number Jim was thinking of was 8! this should be correct, hope this helps!
