11D Expected value, variance and s.d. of the binomial distribution A new test of reading showed that 10% of the students entering high school had a level of reading inadequate to cope with high school. if 400 students are selected at random, find the expected number of students whose reading level is inadequate to cope with high school, determine the standard deviation of students whose reading level is inadequate to cope with high school and hence calculate μ 2σ, discuss the results from b.
