**Instructions for Probability Calculation:**(Be sure to show your work for all the following questions and assume a normal distribution.)**Question:**What is the probability of obtaining a Z score less than -1.0?**Explanation:**To find the probability of obtaining a Z score less than -1.0, look up the Z score in a standard normal distribution table or use a statistical software/calculator that provides the cumulative distribution function (CDF) for the normal distribution.**Graphical Explanation:**- Imagine a bell-shaped curve representing the standard normal distribution (mean of 0 and standard deviation of 1). - The area to the left of the Z score of -1.0 on this curve represents the probability of a Z score being less than -1.0. The graph would show the entire left tail shaded up to the point of Z = -1.0. This shaded area corresponds to the sought probability, which represents all outcomes more extreme than Z = -1.0 in a standard normal distribution.

Given a normal distribution with mean of 14 & standard deviation of 2. What is the P (13 ≤ x ≤ 15)? Write every rule you are going to use
(a) The graph shows a Standard Normal Distribution. You are given 1 or 2 z-score(s) and need to shade the area (=probability) corresponding to: Р(г < 1.6). Click on the "Shade" menu to select the shading option corresponding to the question [to the left, to the right, or between 2 values]. Then slide the arrow to the appropriate z-score. Shade: Left of a value v. Click and drag the arrows to adjust the values. -3 -2 -1 2 4 -1.5 (b) Part 2: you are given an area (=probability), and you need to compute c, which is the z-score that corresponds to the statement: P(z < c) = 0.4 (This is an inverse standard normal distribution problem. Use technology to compute c) The arrow can only be dragged to tick marks that are multiples of 0.1 So, round c to 1 decimal place, and then move the arrow to that rounded value. Click on the "Shade" menu to select the shading option corresponding to the question [to the left, to the right, or between 2 values]. (If the question is less c, choose Left of a…
The formula for finding a z score for an individual value when there is a normal distribution is z = mean – value / Standard deviation True False
A normal distribution has a mean of=100 with a SD= 20 . If one score is randomly selected from this distribution. What is the probability that the score will have a value between X=100 and X=130? NOTE: Using the z-score table attached
True? Determine whether the following statement is true: When random samples of 50 men and 50 women are obtained and we want to test the claim that men and women have different mean annual incomes, there is no need to confirm that the samples are from populations with normal distributions.
Which of the following statements are TRUE about the normal distribution? Check all that apply. __ The area to the left of a z-score plus the area to the right of that same z-score will always equal 1. __ A data value with z-score = -1.5 standard devaitions below the mean. __ The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. __ A z-score is the number of standard deviations a specific data values is from the mena of the distribution. __ The mean corresponds to the z-score of 1.
When can a binomial distribution typically be approximated by a normal distribution? Which of these could work? The sample size being around 30, np and nq both being less than 5, np and nq both being greater than 5, or nx being more than 30?
