Problem #6: 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 13 adults, let X be the number who have been told that they have hypertension. Consider the following probability distribution for X. P(x) ? 1 ? 3 4. ? 5 6 a 7 0.0137 8 0.0032 9 0.0005 10 0.0001 11 0.0000 12 0.0000 13 0.0000 (a) Find the missing entry that is labelled as 'a'. (b) Suppose that a group of 13 adults are randomly selected, and 7 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? Problem #6(a): answer correct to 4 decimals (A) Yes, because 0.0445 is less than .05. (B) No, because 0.0175 is less than .05. (C) No, because 0.0137 is less than .05. (D) Yes, because 0.0137 is less than .05. (E) Yes, because 0.0175 is less than .05. (F) No, because 7 is not a lot more than expected. (G) Yes, because 7 is a lot more than expected. (H) No, because 0.0445 is less than .05. 2.

(a) Find the missing entry that is labelled as 'a'.
(b) Suppose that a group of 13 adults are randomly selected, and 7 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?
Problem #6(a):
answer correct to 4 decimals
(A) Yes, because 0.0445 is less than .05. (B) No, because 0.0175 is less than .05.
(C) No, because 0.0137 is less than .05. (D) Yes, because 0.0137 is less than .05.
(E) Yes, because 0.0175 is less than .05. (F) No, because 7 is not a lot more than expected.
(G) Yes, because 7 is a lot more than expected. (H) No, because 0.0445 is less than .05.
