In a certain population of mussels (mytilus edulis) 80% of the individuals are infected with an intestinal parasite. A marine biologist plans to examine 100 randomly chosen mussels from the population. Let ? represent the number of mussels in this sample with the intestinal parasite.

9) Clearly state the distribution that ? follows, Explain why you picked this distribution? State the distribution we may use to approximate it.

10) Approximate the probability that between 75% and 90% (inclusive) of the mussels in the sample are infected. Note: show your R code for calculating the probability under the normal curve or z-value.

In a certain population of mussels (Mytilus edulis), 80% of the individuals are infected with an intestinal parasite. A marine biologist plans to examine 100 randomly chosen mussels from the population. Find the probability that 85% or more of the sampled mussels will be infected using normal approximation to binomial distribution. What is the expected number of infected mussels in 50 randomly chosen mussels?

In a large population of people, some individuals are infected with a rare disease and some are not. Let POS represent the event that an individual is infected, and let NEG represent the event that an individual is not infected.   A blood test can be administered to try to find out whether an individual is infected. Let represent the event that the test result is positive [i.e., the test indicates that the individual is infected] and let represent the event...

During a winter influenza outbreak, not all exposed individuals are infected. Additionally, some infected individuals display only minor symptoms, while others become seriously ill. Discuss how variations within the population affect survival and fitness using an influenza outbreak as a model to support your explanation.

For a certain group of individuals, the average heart rate is 80 beats per minute, with a standard deviation of 3 beats. If a subject is selected at random, find the following, show your work: a. between 75 and 85 beats per minute. b. between 81 and 86 beats per minute. c. between 76 and 79 beats per minute.

Currently, among the 20 individuals of a population, 2 have a certain infection that spreads as follows: Contacts between two members of the population occur in accordance with a Poisson process having rate ?. When a contact occurs, it is equally likely to involve any of the possible pairs of individuals in the population. If a contact involves an infected and a non-infected individual, then, with probability p the non-infected individual becomes infected. Once infected, an individual remains infected throughout....

1) Suppose that a certain population of 100 individuals possesses two alleles (A and B) at a certain locus, and initially consists of the following numbers of genotypes: AA = 9, AB = 42, BB= 49. a) Calculate the initial frequencies of alleles A and B. b) Now suppose that 16 individuals with genotype BB do not survive to reproduce. Calculate the new allele frequencies among the remaining individuals that do reproduce. Assuming that these remaining individuals mate randomly, calculate...
