Scientists and engineers frequently wish to compare two different techniques for measuring or determining the value of a variable. In such situations, interest centers on testing whether the mean difference in measurements is zero. An article reports the accompanying data on amount of milk ingested by each of 14 randomly selected infants.

Does it appear that the true average difference between intake values measured by the two methods is something other than zero? Determine theP-value of the test, and use it to reach a conclusion at significance level 0.05. Calculate the test statistic andP-value. (Round your test statistic to one decimal place and your
