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="">




    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="">




    B





  • Fail to 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="">




    C





  • Fail to 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.




    D





  • Fail to 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.
