Assume that 10 people join a weight loss program for 3 months. Each person's weight both before and after the program is recorded and the number of pounds each person lost is found.
 
  The following summarizes the results for the 10 people:Mean weight lost = 9 poundsSample standard deviation of weight lost = 4.6 poundsAssume that the hypothesis test will be conducted to determine whether or not the weight loss program is effective using a 0.05 level of significance. What is the value of the test statistic?A) t = 6.19
  B) t = 1.96
  C) z = 1.96
  D) z = 6.19

Q. 2

The Expected Value of Sample Information (EVSI) is ________.
 
  A) the sum of the EMV with sample information (assumed at no cost) and the EMV without sample information
  B) the EMV with sample information (assumed at no cost) minus the EMV without sample information
  C) the EMV without sample information (assumed at no cost) minus the EMV with sample information
  D) the EMV without sample information divided by the EMV with sample information (assumed at no cost)

Q. 3

The more uniform or consistent a process is performing will be seen by ________.
 
  A) a larger value for the range
  B) a predictable value for the range
  C) a smaller value for the range
  D) an infinite value for the range

Q. 4

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
