However, researchers at the University of Minnesota developed a brief, efficientand accurate means of predicting Alzheimer’s is persons from 65 to 85 years of age. The testtakes about 10 minutes and requires the patient to try to recall 10 words after using each wordtwice in sentences. According to the researchers, the test results are accurate 95% of the time.If the test is administered to a random sample of 25 persons from 65 to 85 years of age, what isthe probability that the test results are inaccurate for more than 12% of those persons sampled.Show your work and give your answer in the form of a sentenceYou wish to test the following claim (H.) at a significance level of a 0.02.
