Question

1. According to data in literature, 80% of kidney stones smaller than 6 mm are expected to pass spontaneously. Suppose that in one particular research study, researchers found that of 72 kidney stones smaller than 6 mm, 63 of them passed spontaneously.

a) Can the researchers conclude that the percentage of kidney stones smaller than 6 mm that pass spontaneously is significantly different from the value in the available literature of 80%? Use a significance level of 0.05. Be sure to check that the necessary requirements of the test have been satisfied before performing the test.

b) What does the p-value mean in the context of this problem? Explain the meaning of the p-value referring to the study described in this question.

IMPORTANT NOTE: Please to use the p value method for the question. Conclusions must refer to the actual context of the problem/question being asked. As the question asks to describe things “in the context of the problem”. Make sure that your answer refers to the specific situation being described for this question.
