Hi I'm David and I made you happy answering your question. Now let me bring up your caution here into question. Going to discuss about the company interval from the mean. Let me remind you that the confidence interval for the mean? It has a formula on the X. Bar plus a minus Zn far out with U. Times sigma was good and and the quantity on the right here and it's going to matching her in this question here we are given the sample size and we don't know but we are given that the continental will be within gente. I'm the mean. So it has just done the math general. And we have given the standard Deviation of the population equal to the 80. So we have the sigma equal to the 80 From here. We're also known that we want to compute a native 95% confidence interval. So therefore and far equal to the 5%. And it means then the and far over to eat go to the 2.5%. Which is equal to Deserve 10- five. So if we consider the cesium 10 to 5, The value we found in the Z Temple Equal to the 1.96. So Susan tells us that the marching, The March in a row equal to the two will be one born 96 A de. And we don't know go to the from here and we suffered as good at the end You get equal June the 1.96 Times in the 8th day divided by 20. Now if we remove the squirted and and then we had to square on the right hand side and then we do the calculation. You got to The 61 born 465 56. And the question I want to write you the whole number. And because it's it is a minimum, so we had to write it up to the 62. So the answer for this question will be the 62.
