Elena wants to build a one-sample z interval to estimate what proportion of computers produced at a
factory have a certain defect. She chooses a confidence level of 94%. A random sample of 200 computers
shows that 12 computers have the defect
What critical value z' should Elena use to construct this confidence interval?

here is the

mark brainliest pl

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
