Just need the t and. P value in part B , I will give thumbs up if correct.

Cushing's disease is characterized by muscular weakness due to adrenal or pit itary dysfunction. To provide effective treatment, it is important to detect childhood Cushing's disease as early as possible. Age at onset of symptoms and age at diagnosis (months) for 15 children suffering from the disease were given in an article. Here are the values of the differences between age at onset of symptoms and age at diagnosis. 26 50 11 10 USE s4 27 -15 51 -32 63 -59 70 14 81 21 (a) By far the most frequently tested null hypothesis when data is paired is Ho: up = 0. Is that a sensible hypothesis in this context? Explain. . The statement \":1 = 0 implies that, on the average, the time difference between onset of symptoms and diagnosis of Cushing's disease is months which is unlikely since doctors would not run tests until after a child has shown symptoms of the disease. (b) Carry out a test of hypotheses to decide whether there is compelling evidence for concluding that on average diagnosis occurs more than 25 months after the onset of symptoms. (Use a = 0.05. Use age at onset of symptoms age at diagnosis.) State the appropriate hypotheses. Calculate the test statistic and P-value. (Round your test statistic to one decimal place and your P-value to three decimal places.) t Pvalue
