Question

a new drug is designed to reduce a person blood pressure. 13 randoml selected hypertensive patients recive the new drug. suppose the probability that a hypertensive patient blood presuure drops if he or she is untreated is 0.5. then what is the probability of observing 11 or more blood pressure drops in a random sample of 13 treated patients if the new drug is in fact ineffective in reducing blood pressure? round to six decimal . solve by using binomial distribution table

Answer 1

To calculate the probability of observing 11 or more blood pressure drops in a random sample of 13 treated patients if the new drug is ineffective in reducing blood pressure, we can use the binomial distribution.

Step-by-step explanation:

To calculate the probability of observing 11 or more blood pressure drops in a random sample of 13 treated patients if the new drug is ineffective in reducing blood pressure, we can use the binomial distribution.

1. First, we need to find the probability that a hypertensive patient's blood pressure drops if they are untreated, which is given as 0.5.
2. We can then use this probability to calculate the probability of observing a specific number of blood pressure drops in a sample of 13 treated patients.
3. We can then use a binomial distribution table to find the probability of observing 11 or more blood pressure drops.
4. Round the probability to six decimal places.
