Most companies that make golf balls and golf clubs use a one-armed robot named Iron Mike to test their balls for length and accuracy, but because of swing variations by real golfers, these test robots don't always indicate how the clubs will
 
  perform in actual use. One company in the golfing industry is interested in testing its new driver to see if it has greater length off the tee than the best-selling driver. To do this, it has selected a group of golfers of differing abilities and ages. Its plan is to have each player use each of the two clubs and hit five balls. It will record the average length of the drives with each club for each player. The resulting data for a sample of 10 players are:Player New Club Leading Club1 236.4 237.22 202.5 200.43 245.6 240.84 257.4 259.35 223.5 218.96 205.3 200.67 266.7 258.98 240 236.59 278.9 280.510 211.4 206.5What is the critical value for the appropriate hypothesis test if the test is conducted using a 0.05 level of significance?A) z = 1.645
  B) t = 1.7341
  C) t = 1.8331
  D) t = 2.2622
