- Assume time to failure density function (in months) of transplanted kidneys has a Weibull distribution with shape factor of 3 and scale of 6. Use R and answer the following questions (enter your answers with 3 decimal points):arrow_forwardEagles always lay three eggs at a time. The number of eggs that hatch is described by the following probability distribution: 1. P(X = x) 0.1 0.3 0.4 0.2 Find the mean, variance and standard deviation. Write your solution on your paper. 3.arrow_forwardQ.3. Explain the relationship between the Poisson and exponential distribution.arrow_forward
- A math class completes an exam and it is found that the class mean is 85 and the standard deviation is 2. According to Chebyshev’s Theorem, find the interval for which at least 75% of the grades be.arrow_forwardBinomial distribution probability is based on a. Mean and standard deviation Ob. Number of trials and probability of success Oc. Standard deviation and number of success Od. Mean and probability of successarrow_forwardK Assume that adults have IQ scores that are normally distributed with a mean of μ= 105 and a standard deviation o=15. Find the probability that a randomly selected adult has an IQ less than 126. Click to view page 1 of the table. Click to view page 2 of the table. The probability that a randomly selected adult has an IQ less than 126 is (Type an integer or decimal rounded to four decimal places as needed.)arrow_forward

In Exercises 1–4, assume that scores on a bone mineral density test are normally distributed with a mean of 0 and a standard deviation of 1. Bone Density For a randomly selected subject, find the probability of a score between 0.87 and 1.78.arrow_forward
- A population has u= 50 and o = 5. If 10 points are added to every score in the population, what are the new values for the mean and standard deviation? O -50 and o-15 O -60 and o15 O -50 and a-5 O p-60 and a=5arrow_forwardLenovo produces laptop that last on average by 5 years.
