Hi there,

Can you please help with this?

On average is the younger sibling's 1Q different from the older sibling's 1Q? Ten sibling pairs were given IQ tests. The data are shown below. 10 5cores Younger Sibling 138 127 1:03 Older Sibling 104 101 40 1 05 Assume a Normal distribution. Assume also that we calculated = Younger - Older. What can be concluded at the the @= 0.01 level of significance For this study, we should use | Bloci an arower s. The null and alternative hypotheses would be: Ho: Select an answer W Select an answer w | Select an answer w | (please enter a decimal] H.: Select on answer W Select an answer w | |Eelect on answer w | (Please enter a decimal) After analyzing the data, The following results are found: the sample mean difference x - 7.9, the test statistic is t - -4.145 and the p-value = 0.9026 D. The p-volu: 15 ? v | a C. Based on this, we should | Select an answer w | the null hypothesis. d. Thus, the final conclusion is that ... O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population mean IQ score for younger siblings is not the same as the population mean 10 score for older siblings O The results are statistically stenificant at or = 0.01, so there is sufficient evidence to conclude that the ten younger siblings' IQ scores are not the same on average than the ben older siblings' IQ scores The results are statistically foreignificant at or - 0.01, so there is statistically significant evidence to conclude that the population mean 10 score for younger siblings is equal to the population mean IQ score for older siblings. The results are statistically InGlenificant at o = 0.01, so there is insufficient evidence to conclude that the population mean IQ score for younger siblings is not the same as the population mean IQ score for older siblings
