I get z= 1.40 and so the confidence 91.92% but the book says 84.14%.
Can you check it out please?
Of a random sample of 198 students 98 rated the case of resume inflation as unethical. Based on this info, a statistician computed for the population proportion a confidence interval extending from 0.445 to 0.545. What's the confidence level of this interval?
Thank you for all your help.
So we take off 8.08 from the colored part and we get 91.92-8.08= 83.84.
But it is not 84.14, as in the book. Is it just approximation right? I can be okay with this result? Sorry for being so annoying Thank you so much.
