Assume that adults with smartphones are randomly selected, 48% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that fewer than 4 of them use their smartphone in meetings or classes. The probability is? Round to four decimal places as needed.
3. Let X1, X2, ..., Xn be a random sample from the population N(µz,0²) and Y1, Y2,...,Ym a random sample from the population N(µy, o2), where both means (z and Hy) are assumed known. Note that the two distributions have a common variance of o². (a) If the X's and Y's are independent, show that the MLE for the common variance is: E (Xi - H2)² +E(Y; - Hy)? n+ m (b) Is the MLE found above unbiased for o2?

The probability that a person in the United States has type B+ blood is 8%. Five unrelated people in the United States are selected at random. Complete parts (a) through (d). (a) Find the probability that all five have type B+ blood. The probability that all five have type B+ blood is nothing. (Round to six decimal places as needed.) (b) Find the probability that none of the five have type B+ blood. The probability that none of the five have type B+ blood is nothing. (Round to three decimal places as needed.) (c) Find the probability that at least one of the five has type B+ blood. The probability that at least one of the five has type B+ blood is nothing. (Round to three decimal places as needed.) (d) Which of the events can be considered unusual? Explain. Select all that apply. A. The event in part (a) is unusual because its probability is less than or equal to 0.05. B. The event in part (b) is unusual because its probability is…
10) In a particular class (in another department) the statistics of scores on two midterms and one final revealed the following facts: a) The probability to pass the final is 1/2 b) The probability to pass the final – given that both midterms were passed– is 3/4/. c) The probability to pass the final – given that at least one of the midterms was flunked– is 1/4..d) Passing the first and second midterm are independent events with equal probability. Based on the above information, compute the probability of passing the first midterm.
