Question1- The patient recovery time from a particular surgical procedure… 1- The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.3 days and a standard deviation of 2.1 days.-What is the 75th percentile for recovery times? (Round your answer to two decimal places.)____ days2- In China, four-year-olds average three hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.5 hours and the amount of time spent alone is normally distributed. We randomly survey one Chinese four-year-old living in a rural area. We are interested in the amount of time the child spends alone per day.-70% of the children spend at least how long per day unsupervised? (Round your answer to two decimal places.)3- Suppose that the duration of a particular type of criminal trial is known to be normally distributed with a mean of 25 days and a standard deviation of 6 days.-68% of all trials of this type are completed within how many days? (Round your answer to two decimal places.)_____days-If one of the trials is randomly chosen, find the probability that it lasted more than 28 days.
