Alzheimer’s disease increases in frequency with an increase in age and is responsible for deficits in memory, thinking, judgement and reasoning. Reports show that 10% of Americans over the age of 65 have Alzheimer’s disease. A researcher believes that this proportion is increasing over time and conducts a c hypothesis test. Out of the 100 Americans over the age of 65 in her sample, 15 of them have the disease. Is this enough evidence to show the researcher’s claim is true? Test at 0.05 alpha level.
