Answer #1

Use excel formula "=BINOM.DIST(x, n, p, FALSE)"

x Excel formula P(X=x) [rounded to four decimal places]
6 =BINOM.DIST(6, 10, 0.25, FALSE) 0.0162

Use excel formula "=BINOM.DIST(x, n, p, FALSE)"

x Excel formula P(X=x) [rounded to four decimal places]
8 =BINOM.DIST(8, 10, 0.25, FALSE) 0.0004
9 =BINOM.DIST(9, 10, 0.25, FALSE) 0.0000
10 =BINOM.DIST(10, 10, 0.25, FALSE) 0.0000

Twenty six percent of Canadian men over 35 years have high blood pressure. To run an experiment, a researcher needs to identify at least 20 men with high blood pressure. If the researcher examines 100 men over 35 years, what is the approximate probability he or she nds enough men with high blood pressure to run the experiment? Use the normal approximation to the binomial.

Twenty seven percent of Canadian men over 35 years have high blood pressure. To run an experiment, a researcher needs to identify at least 22 men with high blood pressure. If the researcher examines 100 men over 35 years, what is the approximate probability he or she finds enough men with high blood pressure to run the experiment? Use the normal approximation to the binomial.

Of all people in one population, 21% have high blood pressure and 36% are overweight. In addition, 42% of people who are overweight also have high blood pressure. Let H represent the event that a person has high blood pressure, and O represent the event that a person is overweight. In each part of this question, you must first express each probability in terms of the events H and O and justify any computation through the use of a formula....
