Need help solving this question. Margin of errors

CHALLENGE ACTIVITY 5.7.1: Confidence intervals for population means. 340302 2016390.qx3zqy7 Jump to level 1 Suppose the mean height in inches of all 9th grade students at one high school is 2 estimated. The population standard deviation is 5 inches. The heights of 10 randomly selected students are 75, 67, 71, 74, 71, 74, 73, 71, 63 and 70. x = 70.9 Margin of error at 95% confidence level= Ex: 1.23 95% confidence interval = [ Ex: 12.34 Ex: 12.34 [smaller value, larger value] Check Try again
