A golf ball manufacturer has three dimple patterns it is interested in analyzing to see whether one results in longer driving distances.
 
  However, it also wishes to control for the cover material the ball is made from since it believes that the material might affect driving distance. Four materials can be used. The following data represent the results of tests in which each combination of dimple pattern and cover material were used and the length of the ball hit by a robot has been recorded. The test will be conducted using an alpha = 0.05 level. Pattern 1 Pattern 2 Pattern 3Material A 257 248 260Material B 250 247 255Material C 230 260 240Material D 266 256 280Given these data, which of the following statements is true?A) There is no basis for concluding that mean driving distance is different for the different dimple patterns.
  B) There is no basis for concluding that mean driving distance is different for the different cover materials.
  C) Both A and B are true.
  D) Neither A nor B is true.

Question 2

The Vardon Exploration Company is getting ready to leave for South America to explore for oil. One piece of equipment requires 10 batteries that must operate for more than 2 hours.
 
  The batteries being used have a 15 percent chance of failing within 2 hours. The exploration leader plans to take 15 batteries. Assuming that the conditions of the binomial apply, the probability that the supply of batteries will contain enough good ones to operate the equipment is:A) 0.0449
  B) 0.9832
  C) 0.0132
  D) 0.9964
