1.) Part 1?

Pain: A recent survey asked 826 people how many days they would wait to seek medical treatment if they were suffering pain that interfered with their ability to work. The results are presented in the following table. Number of Days Frequency 29 437 260 74 16 10 Total 826 Send data to Excel Consider these 826 people to be a population. Let X be the number of days for a person sampled at random from this population. Part: 0 / 5 Part 1 of 5 (a) Construct the probability distribution of X. Round the answer to three decimal places. X 0 1 2 3 4 5 X P(x)Determine whether the random variable A has a binomial distribution. If it does, state the number of trials n. If it does not, explain why not. Ten students are randomly chosen from a statistics class of 300 students. Let X be the average grade of these students. Part: 0 / 2 Part 1 of 2 The random variable (Choose one) a binomial distribution. has X 5 does not haveA binomial experiment has the given number of trials n and the given success probability p. n = 8, p = 0.5 Part: 0 / 3 Part 1 of 3 (a) Determine the probability P (1 or fewer). Round the answer to at least four decimal places. P (1 or fewer) =Your flight has been delayed: At Denver International Airport, 81% of recent flights have arrived on time. A sample of 10 flights is studied. Round the probabilities to at least four decimal places. Part: 0 / 4 Part 1 of 4 (a) The probability that all 10 of the flights were on time isWhat should I buy? A study conducted by a research group in a recent year reported that 58% of cell phone owners used their phones inside a store for guidance on purchasing decisions. A sample of 13 cell phone owners is studied. Round the answers to at least four decimal places. (a) What is the probability that seven or more of them used their phones for guidance on purchasing decisions? The probability that seven or more of them used their phones for guidance on purchasing decisions is D . (b) What is the probability that fewer than ten of them used their phones for guidance on purchasing decisions? The probability that fewer than ten of them used their phones for guidance on purchasing decisions is D . (c) What is the probability that exactjy eight of them used their phones for guidance on purchasing decisions? The probability that exactly eight of them used their phones for guidance on purchasing decisions is D . (d) Would it be unusual if more than 10 of them used their phones for guidance on purchasing decisions? It be unusual if more than 10 of them used their phones for guidance on - p WE'LJId since the probability is D . Big Babies: A public health organization reports that 16% of baby boys 6 8 months old in the United States weigh more than 20 pounds. A sample of 12 babies is studied. (a) 1What is the mean number who weigh more man 20 pounds in a sample of 12 babies aged 6 8 months? Round the answer to two decimal places. The mean number who weigh more than 20 pounds is D . (b) What is me standard deviation of the number who weigh more than 20 pounds in a sample of 12 babies aged 6 8 months? Round the answer to four decimal places. The standard deviation of the number who weigh more than 20 pounds is D
