A concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The following data represent the strength of nine randomly selected casts (in psi). 3970, 4100, 3300, 3200, 2940, 3820, 4100, 4030, 3750 Compute the mean, median and mode strength of the concrete (in psi). Lompute the mean strengtn or the concrete. Select the correct cholice below and, IT necessary, Till In the answer box 10 compilete your choice. O A. The mean strength of the concrete is psi of pressure. (Round to the nearest tenth as needed.) () B. The mean does not exist. Compute the median strength of the concrete. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The median strength of the concrete is | | psi of pressure. (Round to the nearest tenth as needed.) () B. The median does not exist. Compute the mode strength of the concrete. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The mode of the strengths of the concrete is | | psi of pressure. (Round to the nearest tenth as needed.) () B. The mode does not exist. The data in the following table show the association between cigar smoking and death from cancer for 132,214 men. Note: current cigar smoker means cigar smoker at time of death. E Click the icon to view the table. (a) If an individual is randomly selected from this study, what is the probability that he died from cancer? (b) If an individual is randomly selected from this study, what is the probability that he was a current cigar smoker? (c) If an individual is randomly selected from this study, what is the probability that he died from cancer and was a current cigar smoker? (d) If an individual is randomly selected from this study, what is the probability that he died from cancer or was a current cigar smoker? (a) P(died from cancer) = Data table (Round to three decimal places as needed.) (b) P(current cigar smoker) = D Died from Did Not Die (Round to three decimal places as needed.) Cancer from Cancer O Never smoked cigars 628 116,940 (c) P(died from cancer and current cigar smoker) = Former cigar smoker 96 7,113 (Round to three decimal places as needed.) Current cigar smoker 175 7,262 Done (d) P(died from cancer or current cigar smoker) = :l (Round to three decimal places as needed.) Determine if the following probability experiment represents a binomial experiment. If not, explain why. If the probability experiment is a binomial experiment, state the number of trials, n, and probability of success, p. A baseball player who gets a hit in 25% of her at bats is asked to take at bats until she gets a hit. The number of at bats attempted is recorded. Select the correct choice below and, if necessary, fill in the answer boxes to complete your answer. O A Yes, because the experiment satisfies all the criteria for a binomial experiment, n = and p=| . (Type integers or decimals. Do not round.) No, because the trials of the experiment are not independent since the probability of success differs from trial to trial. No, because the experiment is not performed a fixed number of times. No, because there are more than two mutually exclusive outcomes for each trial. Assume that the random variable X is normally distributed, with mean p =50 and standard deviation =7. Compute the probability P(38
