Parents with the T allele (tall) and the S allele (short) may produce tall or short offspring. There is a dominant trait T. There is a binomial distribution for tall births, X. The probability of being tall is approximately 0.5. If these parents have 11 children, what is the probability that exactly four of them are tall? How many tall children are expected in a family of 11? In a family with 11 children, how likely is it that at least 2 children are tall? In a class of 300 students, there are three teachers. Upon completion of their first midterm, their grades are normally distributed with a mean of 72% and a standard deviation of 3%. If your grade is more than 80%, what is the probability If your grade is less than 50%, what is the probability In order to be in the top 5% of your class, what grade do you need to achieve? Is there a significant proportion of students with grades between 69 and 79 percent in the class? What are the advantages and disadvantages of this grade distribution
