The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 4.4 mm. Round values to 4 decimal places when possible. The mean of this distribution is The standard deviation is The probability that the round off error for a jumper's distance is exactly 2.1 is P(x = 2.1) = The probability that the round off error for the distance that a long jumper has jumped is between 0 and 4.4 mm is P(1 < x < 3.8) = The probability that the jump's round off error is greater than 1.98 is P(x > 1.98) = P(x > 1.7 | x > 0.6) = Find the 13th percentile. Find the minimum for the upper quartile.
The mileage (in thousands of miles) that car ownersget with a certain kind of radial tire is a random variablehaving an exponential distribution with θ = 40. Find theprobabilities that one of these tires will last(a) at least 20,000 miles;(b) at most 30,000 miles.
Let x be a normally distributed continuous random variable with a mean of 280 and a standard deviation of 28. Determine the value of x such that the area to the left of x is 0.9996. Round the solution to two decimal places, if necessary. x=
The Normal Distribution. The function NORMDIST(x, mu, sigma, TRUE) computes the probability that a normal observation with a fixed mean (mu) and standard deviation (sigma) is less than x. There is also a function for computing the inverse operation: the function NORMINV(p, mu, sigma) computes a value x such that the probability that a normal observation is less than x is equal to P. A. Compute the probability that an observation from a N(3, 5) population is less than 7. B. Find the number x such that P{ N(4, 4) < x } = .75, i.e., such that a normal observation with mean 4 and standard deviation 4 has probability .75 of being less than x. C. If the heights of 17-year-old girls are known to be normally distributed with mean 64 inches and standard deviation 3 inches, how tall must Taylor be when she is 17 so that she will be taller than 73% of other girls her age?
Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading between -2.527°C and -1.641˚C. P(-2.527 < Z < -1.641):
Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading less than -3.226°C.P(Z<−3.226)=
