IQ Scores Younger 107 92 84 96 92 91 103 120 108 |109 Sibling Older 105 87 82 88 86 93 98 112 102 92 Sibling Assume a Normal distribution. What can be concluded at the the a = 0.10 level of significance? For this study, we should use | Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer v Select an answer v|Select an answer v | (please enter a decimal) H1: Select an answer Select an answer v |Select an answer v| (Please enter a decimal) b. The test statistic ? v = (please show your answer to 3 decimal places.) c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is ?v a e. Based on this, we should | Select an answer | the null hypothesis. f. Thus, the final conclusion is that ... O The results are statistically insignificant at a = 0.10, so there is statistically significant evidence to conclude that the population mean IQ score for younger siblings is equal to the population mean IQ score for older siblings. The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the ten younger siblings' IQ scores are not the same on average than the ten older siblings' IQ scores. The results are statistically significant at o = 0.10, so there is sufficient evidence to
