Please answer as soon as possible. Thumbs up for all answers, thank you! 1) Random variable Z has a Gaussian distribution with µZ = 0 and σZ = 1. What is the mean value of -0.24Z + 0.36? 2) Random variable Z has a Gaussian distribution with µZ = 0. What is the probability that Z > 0? 3) Random variable X is continuously and uniformly distributed over the range 0 to 1. What is σX, the standard deviation of...
An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11 4 minutes. A random sample of 34 dive durations has a mean of 12 2 minutes and a standard deviation of 23 minutes. At a=001 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Identify the claim and state (b) Use technology to find the P-value. Find the standardized test statistic, (Round to...
Suppose that the duration of a particular type of criminal trial is known to be normally distributed with a mean of 23 days and a standard deviation of 6 days. If one of the trials is randomly chosen, find the probability that it lasted more than 26 days. Write the probability statement and the amount of this probability. Use 4 decimal places in your probability. ex. of probability statements: P(a < X < b), P(X < a), P(X > a)

5. The entry in the standard normal table is 0.1131, what is the associated 2-score? [1 mark] 6. Using the standard normal table, determine the probability that... [4 marks] a. X<-0.11 b. X > 1.46 c. 0.15 < X < 2.00
The time required for Dr. B's students to complete the Statistics Exam is approximately normally distributed with a mean of 40.4 minutes and a standard deviation of 2.2 minutes. Let X be the random variable "the time required for Dr. B's students to complete the Statistics Exam." 6. With the above setting what time marks the 90th percentile? A. 37.562 minutes B. 37.584 minutes C. 43.238 minutes D. 43.216 minutes E. None of the above 7. Which of the following...
I need its answer as soon as possible. Write a C program that uses malloc to find the sum on a 1-D int array that holds 1000 integers, incriminating from 1. Also share the output and discuss what you have learned to complete the task.
Education researchers estimate that a student’s score y on the PLAANET exam and the number of days x spent preparing for it are related by the linear model y = 3x + 11 + where is normally distributed with a mean of 0 and standard deviation of 2. Find the probability that a student who studies 12 days will make a score less than 50.
Question 1 of 21 4 Points You get this question on an exam: "Assume that the length of time needed to play a round of miniature golf at Noel's Funland is normally distributed with mean u = 45 minutes, and a standard deviation o = 10 minutes. If you randomly sample 25 players, what is the probability that the average for the 25 will exceed 50 minutes?" You solve the problem and get an answer. Now you are asked to...
