Which conclusions are supported by the p-value? check all that are valid. Group of answer choices the data from this study does not suggest that the amount of sleep for lmc students differs from the national average of 6. 9 hours. This sample of lmc students sleep on average 7. 12 hours, but the difference between this and the hypothesized population mean of 6. 9 hours is not statistically significant and could be explained by predictable variation that occurs in random sampling. The data from this sample provides strong evidence that the average amount of sleep on a weeknight for lmc students differs from the national average of 6. 9 hours. The difference between the 7. 12 sleep hours for lmc student average and the 6. 9 hours for the national average is statistically significant. Fail to reject the null hypothesis reject the null hypothesis and accept the alternative. Accept the null hypothesis
