A two-sample t-test for a difference in means was conducted to investigate whether there is a statistically significant difference in the average amount of fat found in low-fat yogurt and the average amount of fat found in nonfat yogurt. With all conditions for inference met, the test produced a test statistic of t=2.201 and a p-value of 0.027. Based on the p-value and a significance level of α=0.05, which of the following is the correct conclusion? Reject the null hypothesis because p<α. The difference in the average amount of fat found in low-fat and nonfat yogurt is not statistically significant. A Reject the null hypothesis because p<α. The difference in the average amount of fat found in low-fat and nonfat yogurt is statistically significant. B Fail to reject the null hypothesis because p<α.

Use the dataset HT_4541.xls. Using Excel, conduct a t-test (at the alpha = 0.01 significance level) on whether the mean of X1 is equal to 100. What do you conclude from this sample data? Is the population mean equal to 100? Group of answer choices a-You reject the null hypothesis. You conclude that the population mean is equal to 100. b-You cannot reject the null hypothesis. You conclude that the population mean is equal to 100. c-You reject the null hypothesis. You conclude that the population mean is not equal to 100. d-You cannot reject the null hypothesis. You conclude that the population mean is not equal to 100. HT_4541.xls.
