Some measurement on a population has a normal distribution with expectation of 1000 and standard deviation of 150. we denote difference between the 0.75-percentile and the 0.25-percentile the interquartile range. identify a measurement value as outlier if it is larger than the 0.75-percentile plus 1.5 times the interquartile range or it is smaller than the the 0.25-percentile minus 1.5 times the interquartile range. a. the 0.25-percentile of the measurement isb. the 0.75-percentile of the measurement isc. the interquartile range of the measurement isd. the probability that a random measurement will be identified as outlier is
