Consider a x distribution with 9 degrees of freedom. Find P(x < 11.5). Find P(x > 9.8). Find P(7.7 < x < 17.3).

Mark has a batting average of 0.17. Let X be the number of hits in his next 16 at bats. What is the distribution of X? X      (,) Please show the following answers to 4 decimal places. What is the probability that he has exactly 7 hits? 0.0088 What is the probability that he has less than 7 hits?

Where appropriate, work the followingbinomial distribution problem by using thenormal curve.P(x≥ 13 | n = 20 and p = 0.60) =

Let X be b(2, p) (binomial distribution). Assume P(X > 1) = (a) Find p. (b) Compute P[X = 2]. %3D

A random number generator picks a number from 6 to 65 in a uniform manner. Round answers to 4 decimal places when possible. The mean of this distribution is   . The standard deviation is   . The probability that the number will be exactly 48 is    P(x=48)=P(x=48)=   . The probability that the number will be between 17 and 22 is    P(17<x<22)=P(17<x<22)=   . The probability that the number will be larger than 50 is    P(x>50)=P(x>50)=   . P(x>24∣x<57)=P(x>24∣x<57)=   . Find the 21st percentile.   Find the minimum for the upper quarter.

The mean amount of time it takes a kidney stone to pass is 13 days and the standard deviation is 6 days. Suppose that one individual is randomly chosen. Let X = time to pass the kidney stone. Round all answers to 4 decimal places where possible.a. What is the distribution of X? X ~ N(  ,  ) b. Find the probability that a randomly selected person with a kidney stone will take longer than 9 days to pass it. ___c. Find the minimum number for the upper quarter of the time to pass a kidney stone. ___ days.

The duration of a professor's class has a continuous uniform distribution between 50.0 minutes and 52.0 minutes. If one class is randomly selected, find the probability that the professor's class duration is between 50.4 and 51.8 minutes.P(50.4<X<51.8)

In a t distribution, the critical values will always be the same (not dependent on sample size).TrueFalse

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is less than 51 min.P(X < 51) =
