Phone calls can be classified as voice (V) if someone is speaking, or data (D) if there is a modem or fax transmission. Based on many observations made by the telephone company, we have the following probability model: P [V] = 0.8, P [D] = 0.2. Data calls and voice calls are produced independently. The random variable Kn is the number of data calls in a collection of n calls telephone (a) What is the E [K100], the expected number...

Joe, a basketball player, claims that he makes at least 60% of his basketball free throws. Assuming that he attempts 20 free throws, use an exact binomial distribution to evaluate Ho: p = 0.6 against a one-sided alternative that his success percentage is lower than 0.6. Let X be the number of free throws made. Which rejection region is the most appropriate for this test and why? ?1 = {?|? ≤ 8} ?2 = {?|? ≥ 16} ?3 = {?|?...
