Reference no: EM13108213

If you are performing a hypothesis test using a z statistic in which you sampled 50 people and found an average SAT verbal score of 542 (assume we know the population mean to be 500 and the standard deviation to be 100), calculate the mean and spread of the comparison distribution (lM and rM).
