1. The management of the seaside golf club regularly monitors the golfers on its course for speed of play. Suppose a random sample of golfers was taken in 2005 and another random sample of golfers was selected in 2006. The results of the two samples are as follows: 2005 x bar 1=225 s1=20.25 n1=36 2006 xbar=219 s2=21.70 n2=31 based on the sample results, can the management of the seaside golf conclude that the average speed of play was different in 2006 that in 2005? Conduct the appropriate hypothesis test at the 0.10 level of significance. Assume that the management of the club is willing to accept the assumption that the populations of playing times for each year are approximately normally distributed with equal variance.
