P(x<78) P(x<78) = (Round to four decimal places as needed.)According to a study, the time between taking a pain reliever and getting relief for a randomly selected patient has unknown distribution with a mean of 48 minutes and a standard deviation of 5.8 minutes. Let X be the time between taking a pain reliever and getting relief for a randomly selected patient and let X be the average time between taking a pain reliever and getting relief for a random sample of size 43. 1. Describe the probability distribution of X and state its parameters u and o: X- Select an answer and find the probability that the time between taking a pain reliever and getting relief for a randomly selected patient is more than 53 minutes. (Round the answer to 4 decimal places) 2. Use the Central Limit Theorem Select an answer to describe the probability distribution of X and state its parameters uz and oy: (Round the answers to 1 decimal place) X - Select an answer v (µx ,ox = and find the probability that the average time between taking a pain reliever and getting…Let x be a random variable that represents the level of glucose in the blood (milligrams per deciliter of blood) after a 12-hour fast. Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean μ = 93 and estimated standard deviation σ = 38. A test result x < 40 is an indication of severe excess insulin, and medication is usually prescribed. (a) What is the probability that, on a single test, x < 40? (Round your answer to four decimal places.)(b) Suppose a doctor uses the average x for two tests taken about a week apart. What can we say about the probability distribution of x? Hint: See Theorem 7.1. The probability distribution of x is approximately normal with μx = 93 and σx = 38.The probability distribution of x is approximately normal with μx = 93 and σx = 26.87. The probability distribution of x is approximately normal with μx = 93 and σx = 19.00.The probability distribution of x is not normal. What is the probability that x…
