Suppose we are dealing with a quantitative recessive trait, which is distributed as N(μ, 1) when there are two variants, and N(0, 1) otherwise. Calculate the probability that a randomly selected person with two variants has a trait higher than a person with one or no variants, when μ = 0.5, and when μ = 2.

Suppose IQs are normally distributed with a mean of 100 and a standard deviation of 16. a) If one person is randomly selected, what is the probability that the person’s IQ is higher than 90 but lower than 115? b) If eight people are randomly selected, what is the probability that the sample mean IQ is higher than 90 but lower than 115?

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean of μ=271 days and standard deviation o=26 days. Complete parts (a) through (f) below. (a) What is the probability that a randomly selected pregnancy lasts less than 263 days? The probability that a randomly selected pregnancy lasts less than 263 days is approximately 0.3783. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer...

5. Let y|μ ~ N(μ, φ), where φ is known. There is no reliable prior information about the mean other than that it is expected to be a positive quantity. Therefore, use the improper prior distribution: p(p)-1 if (0,x) and 0 otherwise. Suppose we observe one y. Then, find the posterior mean of p. (obtain an explicit expression)
