There is not sufficient evidence to conclude that the mean price of a single-family home has increased from its level two years ago of $299,100. O B. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased from its level two years ago of $299,100. O C.

11.5.332 Question Help Researchers wanted to measure the effect of alcohol on the development of the hippocampal region in adolescents. The researchers randomly selected 11 adolescents with alcohol use disorders. They wanted to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x 8.43 and s 0.6. Conduct an appropriate test at the a = 0.01 level of significance. E Click here to view the t-Distribution Area in Right Tail. Choose the correct answer below. O A. Reject H, since the test statistic is not less than the critical value. O B. Reject H, since the test statistic is less than the critical value. O C. Do not reject H, since the test statistic is less than the critical value. D. Do not reject Ho since the test statistic is not less than the critical value. i t-Distribution Area in Right Tail %3 t-Distribution Arca in Right Tail df 0.25 0.20 0.15 0.10 0.05 0.025 0.02 0.01 0.005 12.706 4.303 3.182 2.776 2571 15.894 4.849 3.482 2.999 2.757 31.821 6.965 4.541 3.747 3.365 63.657 9.925 5.841 4.604 4.032 1.376 1.963 1.386 1250 1190 1.156 3.078 1.886 1.638 1.533 1.476 6.314 2.920 2.353 2.132 2.015 1.000 0.816 0.765 0.741 0.727 1.061 0.978 0.941 0.920 2345
