Asimple random sample of size n is drawn from a normally distributed population, and the mean of the sample is , while the standard deviation is s. what is the 99% confidence interval for the population mean? use the table below to you answer the question. confidence level 90% 95% 99% z*-score 1.645 1.96 2.58

99% confidence level which is 2.58.

step-by-step explanation:

we have been given confidence level and z-score.

we have the formula for z-score which is:

according to the table given:

since, we have been asked 99% confidence level which is 2.58.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
