Much concern has been expressed regarding the practice of using nitrates as meat preservatives. In one study involving possible effects of these chemicals, bacteria cultures were grown in a medium containing nitrates. The rate of uptake of radiolabeled amino acid (in dpm, disintegrations per minute) was then determined for each culture, yielding the following observations:7251687196326866909458 49895779787064749478838178752387247 468Suppose that it is known that the mean rate of uptake for cultures without nitrates is 8000.Does the data suggest that the addition of nitrates results in a decrease in the mean rate of uptake? Test the appropriate hypotheses using a significance level of 0.10.
