The observed sample mean produced a t statistic test statistic of -0.18489. We use the t Distribution Calculator to find P (t < -0.18489) = 0.253. This means we would expect to find a sample mean of 15.85 or smaller in 25.3% of our samples, if the true ounces were 16. Thus, the P-value in this analysis is 0.19. Interpret results. Since the P-value (0.253) is greater than the significance level (0.01), we cannot reject the null hypothesis. Conclusion: There is evidence from these data and results to suggest that a bottle contains less than 16 ounces. Question 4 The causes for less ounces in the soda can be due to inefficiency with the machines, due to old age of the machines it can lead ...
