- Find the Z score for which 80% of the distributions area lies between -z and zUse the formula for mean of a continuous distribution to calculate the mean of the following exponential distribution with density function:Suppose that a random variable X has a continuous uniform distribution - Find the distribution of the sample mean of a random sample of size n = 40. - Plot the density curve.
- What is the number called that determines each unique T distribution?Find the uniform distribution of the continuous type on the interval (b, c)that has the same mean and the same variance as those of a chi-square distributionwith 8 degrees of freedom. That is, find b and c.Find the z-scores for which 88% of the distribution's area lies between −z and z.
- Find the z -scores for which 90% of the distribution's area lies between −z and z .Let X be a continuous random variable with the following pdf: If needed, round to FOUR decimal places.the continuity correction is used to compensate for the fact that ___ distribution is used to approximate a ___ distribution a) discrete; continuous b) continuous; discrete c) discrete; uniform d) binomial; uniform
- Define the t distribution of meansA surveyor wishes to lay out a square region with each sidehaving length L. However, because of a measurement error,he instead lays out a rectangle in which the north–south sides both have length X and the east–west sides both have lengthY. Suppose that X and Y are independent and that each isuniformly distributed on the interval [L 2 A, L 1 A] (where0 , A , L). What is the expected area of the resultingrectangle?Suppose that variable z has a standard normal distribution. Use the attached table to findthe particular z value (zo) that satisfies(a) Pr (z ≥ zo) = .0099,(b) Pr (z ≤zo) = .8907, (c) Pr(z ≤ zo) = .0179,(d) Pr(z ≥ zo) = .6985,(e) Pr(-zo ≤ z ≤ zo) = .5762, (f) Pr(zo ≤ z ≤1.00) = .7056.
