Is it significant? In the absence of special preparation SAT mathematics(SATM) scores in recent years have varied Normally with mean = 518 and = 114. Fifty students go through a rigorous training program designed to raisetheir SATM scores by improving their mathematics skills. Either by hand or byusing the P-Value of a Test of Significance applet, carry out a test ofH0: = 518 Ha: > 518(with = 114) in each of the following situations:(a) The students average score is x = 544. Is this result significant at the 5%level?(b) The average score is x = 545. Is this result significant at the 5% level?The difference between the two outcomes in (a) and (b) is of no importance.Beware attempts to treat = 0.05 as sacred.
