Samuel F.B. Morse (1791 – 1872), the creator of Morse Code, claimed that 12% of all letters used in the English language were “e”s.  Suppose random samples of 196 letters are selected from a book. Use this information to answer questions  What is the probability that a random sample of 196 letters will contain at least 10% "e"s? Type your calculated z-score here. Express its value to the nearest hundredth (two decimal places)______ Type your probability here. Express its value to four decimal places._________

A geneticist constricts an experiment with peas, one sample of offspring consisted of 460 green peas and 143 yellow peas. Based on the results, estimate the probability of getting an offspring pea that is green. Give answer using the appropriate rounding rule

Seventy percent of bicycles sold by a certain store are mountain bikes. Let X be the number of 100 randomly selected purchases that are for mountain bikes. Verify the binomial setting. Verify that the sampling distribution of X is approximately normal. What is the approximate probability that At most 75 are mountain bikes? Between 60 and 75 (inclusive) are mountain bikes? More than 80 are mountain bikes?
