Construct a 90% confidence interval to estimate the population mean using the accompanying data. What assumptions need to be made to construct this interval? x= 85 o = 20 n= 16 What assumptions need to be made to construct this interval? A. The population must be normally distributed. O B. The population is skewed to one side. OC. The population mean will be in the confidence interval. O D. The sample size is less than 30. With 90% confidence, when n= 16, the population mean is between the lower limit of (Type integers or decimals rounded to two decimal places as needed.) and the upper limit of.
