10. A golf association requires that golf balls have a diameter that is 1.68 inches. To determine if golf balls conform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the a = 0.05 level of significance. Click here to view the data on golf ball diameters." Click here to view the table of critical t-values. 10 First determine the appropriate hypotheses Ho : (1 ) (2) H 1 : (3 ) (Type integers or decimals. Do not round.) Find the test statistic. (Round to two decimal places as needed.) Approximate the P-value. The P-value is in the range (5) What can be concluded from the hypothesis test? A. Do not reject Ho. There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the a = 0.05 level of significance. O B. Reject Ho. There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the a = 0.05 level of significance. O C. Do not reject Ho. There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the a = 0.05 level of significance. O D. Reject Ho. There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the o = 0.05 level of significance. 9: Golf Ball Diameters Golf Ball Diameter (inches) 1.682 1.676 1.683 1.686 1.677 1.684 1.684 1.685 1.673 1.685 1.682 1.675 10: Critical T-values - Area in right tail [-Distribution Area in Right Tail df 0.25 0.20 0.15 0.10 0.05 0.025 0.02 0.01 0.005 0.0025 0.001 0.0005 df 318.309 636.619 1.000 1.376 1.963 3.078 6.314 12.706 15.894 31.821 53.657 127.321 0.816 1.061 1.386 1.886 2.920 4.303 4.849 6.965 0 925 14.089 22.327 31.599 0.978 1.250 1.638 2-353 3.182 3.482 5.841 7.453 10.215 12.924 AMAGNE 0.765 4.541 UIAWN 0.941 1.190 1533 2.132 2.776 2.999 3.747 4.604 5.598 7.173 3.610 0.741 0.727 0.920 1.156 1.476 2.015 2.571 2.757 3.365 4.032 4.773 5.893 6.869 0.718 0.906 1.134 1.440 1.943 2.447 2.612 3.143 3.707 4.317 5.208 5.959 0.711 0.896 1.119 1.415 1.895 2.365 2.517 2.998 3.499 4.029 4.785 5408 0.706 0.889 1.108 1.397 1.860 2.306 2.449 2.896 3.355 3.833 4.501 5.04 0.703 1.100 4,781 0.883 1.383 1.853 2262 2.398 2821 3250 3.690 4.297 0.879 1.093 1.372 1.812 2.228 2.359 2,76 3.169 4.144 4.587 10 0.700 3.581 0.697 0.876 1.088 1.363 1.796 2.201 2.328 2.718 3.106 3.497 4.025 4.437 11 4.318 12 3.930 0.695 0.873 1.083 1.782 2.179 2 303 2.681 3.055 3.428 1.350 1.771 2.160 2.282 2.650 3.012 3.372 3.852 4.221 13 0.694 0.870 1.079 14 0.692 0.868 1.076 1.345 1.761 2.145 2.264 2.624 2.977 3.326 3.787 4.140 14 15 0.866 1.074 1.341 1.753 2.131 2.249 2.602 2 947 3.286 3.733 4.073 15 0.691 0.690 0.865 1.071 1.337 1.746 2.120 2235 2.583 2.921 3.252 3.686 4.015 16 16 17 0.68 0.863 1.069 1.333 1.740 2.110 2.224 2.567 2.898 3 222 3.646 3.96 17 3.197 3.922 18 18 0.688 0.862 1.067 1.330 1.734 2.101 2.214 2.552 2.878 3.610 19 2.861 3.174 3.883 19 0.688 0.861 1.066 1.328 1.729 2.093 2.205 2.539 3.850 20 20 0.687 0.860 1.064 1.325 1.725 2.086 2.197 2528 2.845 3.153 3.552
