ul Verizon LTE 3:21 PM Touch to return to Navigation Homework: Section 7-3 HW Score:Oof5pts ' 4 ' Tof8(5 completelv | b i HWS *7.3.33| The random sample shown below was selected from a normal distribution. 3.6.8.4,6.9 in Complete parts a and b. :1. Construct a 95% condence interval for the population mean '1. ( 3.61 . 8.39 J (Round to two decimal places as needed.) b. Assume that sample mean 1-: and sample standard deviation s remain exactly the same as those you just calculated but that are b observations. Repeat part a. What is the effect of increasing the sample size on the width of the condence intervals? The condence interval is 03.0 . (Round to two decimal places as needed.)
