A researcher wants to estimate the average age of patients newly diagnosed with type II diabetes mellitus in a certain adult population. From a sample of 10 subjects, the average age at the time of diagnosis was 45.8 years and the population standard deviation is 12.5 years. If the population from which the sample was drawn follows a normal distribution. We wish to prove that the average age of diagnosis of these patients is different from 50 years through a hypothesis test, using 5% significance. What is the conclusion for this analysis? A. The age at diagnosis of these patients is different from 50 years. B. The age at diagnosis of these patients is not different from 50 years. C. The age at diagnosis of these patients is over 50 years. D. The age at diagnosis of these patients is less than 50 years.
