Suppose the preliteracy scores of three-year-old students in the United States are normally distributed. Shelia, a preschool teacher, wants to estimate the mean score on preliteracy tests for the population of three-year-olds. She draws a simple random sample of 20 students from her class of three-year-olds and records their preliteracy scores (in points). 74, 79, 83, 85, 88, 90, 94, 95, 95, 97,99, 99, 100, 103, 105, 105, 106, 107, 107, 108 Click to download the data in your preferred...
