Question 14: Suppose that, conditional on N, X has a Binomial distribution with N trials and probability of success p, and that N, itself, is a Binomial distribution with m trials and probability of success r. Find b. The conditional distribution of given X-x.
Suppose X ~ N(2, 3). What value of x has a z-score of three?
Suppose X ~ N(2, 3). What value of x has a z-score of -0.67? If the area to the left of x in a normal distribution is 0.161, what is the area to the right of X?
Suppose X~N(4, 2). a) What value of x is 1.5 standard deviations to the left of the mean? b) What is the 90th percentile of X? Express your answers with 3 decimals.
Suppose X ~ N(3, 2). What value of x is two standard deviations to the right of the mean? (Enter an exact number as an integer, fraction, or decimal.) x =
(5,3,-2) Evaluate the integral y dx + x dy + 4 dz by finding parametric equations for the line segment from (2,1,5) to (5,3,-2) and evaluating the line integral of (2,1,5) F = yi + x3 + 4k along the segment. Since F is conservative, the integral is independent of the path. (5,3,-2) y dx + x dy + 4 dz= (2,1,5)
Question 2 2 pts Suppose F(x) = 2x+1 To the nearest thousandth, what is the value of F'(21)?
Suppose X ~ N(8, 6). What value of x has a z-score of -0.4? x = ______? Round to one decimal place. If your answer is a whole number, just type that number without a decimal.
Suppose X ~ N(8, 1). What value of x has a z-score of −1.25? (Enter an exact number as an integer, fraction, or decimal.) x=
suppose x~N(5,2.1). what x- value is 1.8 standard deviations to the left of the mean? round answer two decimal places
