Use complete sentences to answer each question. THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: The distribution of IO scores for high school graduates is normally distributed with mean p =104 and standard deviation 0 = 16. 1) Find the probability a person chosen at random from this group has an IQ score above 146.00 2) What fraction of the IQ scores would be between 97 and 126? 3) What Is the 95th percentile of this normal distribution? THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: Times spent studying by students In the week before nal exams follow a normal distribution with standard deviation 9 hours. A random sample of 5 students was taken in order to estimate the mean study time for the population of all students. 4) What is the standard error of the sampling distribution for the mean score? 5) What is the probability that the sample mean exceeds the population mean by more than 2.1 hours
