The area between 2 = - 1.1 and z = 1.3 under the standard normal curve is El. (Round to four decimal places as needed.) Find the indicated probability using the standard normal distribution. P(z > 0.31) Click here to view page 1 of the standard normal table. Click here to view page 2 of the standard normal table. <:> P(z > 0.31 ) = D (Round to four decimal places as needed.) Assume the random variable x is normally distributed with mean u = 50 and standard deviation 6 = 7. Find the indicated probability. P(x > 43) <: p>43)= D (Round to four decimal places as needed.) In a survey of a group of men, the heights in the 2029 age group were normally distributed, with a mean of 67.3 inches and a standard deviation of 4.0 inches. A study participant is randomly selected. Complete parts (a) through (d) below. (:i (a) Find the probability that a study participant has a height that is less than 65 inches. The probability that the study participant selected at random is less than 65 inches tall is D. (Round to four decimal places as needed.) (b) Find the probability that a study participant has a height that is between 65 and 70 inches. The probability that the study participant selected at random is between 65 and 70 inches tail is D. (Round to four decimal places as needed.) (c) Find the probability that a study participant has a height that is more than 70 inches. The probability that the study participant selected at random is more than 70 inches tall is D. (Round to four decimal places as needed.) (d) Identify any unusual events. Explain your reasoning. Choose the correct answer below. {2:} A. The events in parts (a) and (c) are unusual because its probabilities are less than 0.05. '11:} B. There are no unusual events because all the probabilities are greater than 0.05. {j} C. The event in part (a) is unusual because its probability is less than 0.05. (:21- D. The events in parts (a), (b), and (c) are unusual because all of their probabilities are less than 0.05
