The percentage of adults who have at some point in their life been told that they have hypertension is 23.53%. In a sample of 10 adults, let X be the number who have been told that they have hypertension. Consider the following probability distribution for X. x P(X) 0? 1 ? 2 ? 3 ? 4? 5 a 6 0.0122 7 0.0021 8 0.0002 9 0.0000 10 0.0000 (a) Find the missing entry that is labelled as 'a. (b) Suppose that a group of 10 adults are randomly selected, and 6 of them have been told that they have hypertension. Is this a significantly high number that would suggest that the given percentage of adults who have been told that they have hypertension (i.e., 23.53%) is not correct?
