## TestHO - Mean Question 12 (4 points) Saved The Lawnpoke Golf Association (LGA) has established rules that manufacturers of golf equipment must meet for their products to be acceptable for LGA events. BatOutaHell Balls uses a proprietary process to produce balls with a mean distances of 295 yards. BatOutaHell is concerned that if the mean distance falls below 295 yards, the word will get out and sales will sag. Further, if the mean distance exceeds 295 yards, their balls may be rejected by LGA. Measurements of the distances are recorded in DATA. At = 0.05, test the no action hypothesis that the balls have a mean distance of 295 yards. The test statistic -1.297 is inside the acceptance region (-2.101, +2.101). It does not exceed either the lower or upper critical values. The null hypothesis HO is not rejected. The mean distance is about 295 yards. The test statistic is 3.003 and the critical value is 1.734, therefore the test statistic is greater than the critical value of 1.734 and the null hypothesis is rejected. The distance is not 295 yards. None of the answers match my calculation. The test statistic of 1.908 is greater than the critical value of 1.734, therefore HO is rejected. It is reasonable to assume that the distance is not 295 yards. The test statistics of 2.238 is greater than the critical value of 1.734, therefore HO is rejected. It is reasonable to assume that the distance is not 295 yards.
