According to a study, the time between taking a pain reliever and getting relief of a randomly selected patient is normally distributed with a mean of 38 minutes and a standard deviation of 4.2 minutes. Let XX be the time between taking a pain reliever and getting relief for a randomly selected patient and let ¯¯¯XX¯ be the average time between taking a pain reliever and getting relief for a random sample of size 16. 1. Describe the probability distribution of XX and state its parameters μμ and σσ: X∼X∼ ( μ=μ= , σ=σ= ) and find the probability that the time between taking a pain reliever and getting relief for a randomly selected patient is between 26 and 47 minutes. (Round the answer to 4 decimal places) 2. Use the Central Limit Theorem to describe the probability distribution of ¯¯¯XX¯ and state its parameters μ¯¯¯XμX¯ and σ¯¯¯XσX¯: (Round the answers to 1 decimal place) ¯¯¯X∼X¯∼ ( μ¯¯¯X=μX¯= , σ¯¯¯X=σX¯= ) and find the probability that the average time…
The strength of the cubic concrete of the first line production is 110 N/mm² and standard deviation =12 N/mm² and for the second line production is 95 N/mm² and standard deviation =10 N/mm². If two samples are taken from each line, n=100X for each and the strength are tested, find the probability that the strength of 1 line greater than the 2nd line by: a- 17 N/mm² or more b- 35 N/mm² or more x=0.74
Use the result of Exercise 45 to show that, if n independent random variables Xi have normal distribu-tions with the means μi and the standard deviations σi, then Y = a1X1 + a2X2 +···+ anXn has a normal dis-tribution. What are the mean and the variance of this distribution?
The Rockwell hardness of a metal is determined byimpressing a hardened point into the surface of themetal and then measuring the depth of penetration of thepoint. Suppose the Rockwell hardness of a particularalloy is normally distributed with mean 70 and standarddeviation 3.a. If a specimen is acceptable only if its hardness isbetween 67 and 75, what is the probability that a randomlychosen specimen has an acceptable hardness?b. If the acceptable range of hardness is (70 2 c, 70 1 c),for what value of c would 95% of all specimens haveacceptable hardness?c. If the acceptable range is as in part (a) and the hardnessof each of ten randomly selected specimens isindepen-dently determined, what is the expectednumber of acceptable specimens among the ten?d. What is the probability that at most eight of ten independentlyselected specimens have a hardness of lessthan 73.84? [Hint: Y 5 the number among the tenspecimens with hardness less than 73.84 is a binomialvariable; what is p?]
