An IQ test is designed so that the mean is 100 and the standard deviation is 13 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with
95% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o = 13 and determine the
required sample size using technology. Then determine if this is a reasonable sample size for a real world
calculation

answerthe vertex form

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

is there any answers choices? l can try to you if there is answer choices to this question,so sorry
