12) Balls uses a proprietary process to produce balls with a mean distances of 295 yards. Balls is concerned that if the mean distance falls below 295 yars, the word will get out and sales will sag. If the mean distance exceeds 295 yards, their balls may be rejected. Measures of the distance are recorded in data. at (greek symbol x)= 0.05, test the no action hypothesis that the balls have mean distance of 295 yards.

data:

293//275//280//290//273//306//287//301//309//285//274//282//294//283//304//297//294//290//283

a) test statistic is 1.908 is greater than the critical value of 1.734

b) test statistic is 3.003 and the critical value is 1.734

c)test of 2.238 is greater than critical value of 1.734
