A research study uses 50 men under the age of 55. Suppose that 30% carry a marker on the male chromosome that indicates anincreased risk for high blood pressure. Use the hypergeometric distribution to find the following probabilities.Round your answers to three decimal places (e.g. 98.765).(a) If 6 men in the study are tested for the marker in this chromosome, what is the probability that exactly 1 man has the marker?Probability i(b) If 6 men in the study are tested for the marker in this chromosome, what is the probability that more than 1 has the marker?Probability = i

Given Information: There are 50 men i.e., N=50 30% carry a marker on the male chromosome so, p=0.30…

Answered: A research study uses 50 men under the…

A professor knows that her statistics students' final exam scores have a mean of 80 and a standard deviation of 12.2. In her class, an "A" is any exam score of 90 or higher. This quarter she has 25 students in her class. What is the probability that 7 students or more will score an "A" on the final exam?Hint: You will need to use your knowledge of normal probability distributions to determine the probability of one individual getting an A and then use your knowledge of binomial distributions to determine the probability of 7 students or more out of 25 students getting an A.prob = ____________Report your final answer accurate to 4 decimal places. Do not round any of the numbers in this calculation until the very end of the problem!
