The Lawnpoke Gold Association (LGA) has

established rules that manufacturers of gold equipment must meet for their products to be acceptable for LGA events. GatOutaHell 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 below. At proportional to = 0.05, test the no action hypothesis that the balls have a mean distance of 295 yards.
