WebbWe can do this by finding the area to the left of 4.85 and subtracting it from 1: Probability = 1 - right area Probability = 1 - 0.26 Probability = 0.74. Therefore, the probability that a randomly chosen senior will have a GPA greater than 4.85 is 0.74. Part 3: Using a TI-84 Plus calculator, we can find the area under the standard normal curve ... WebbUsing the TI-84 Plus calculator, find the area under the standard normal curve that lies between the following z -values. Round the answers to at least four decimal places. (a) Find the area under the standard normal curve that lies between =z−2.27 and =z0.36. Question 3: A normal population has mean =μ9 and standard deviation =σ6.

WebbNormal Distribution Problems and Solutions Question 1: Calculate the probability density function of normal distribution using the following data. x = 3, μ = 4 and σ = 2. Solution: … WebbThis shows that the area between X 1 and X 2 is the probability as stated in the formula: P (X 1 ≤ x ≤ X 2) . The mathematical tool needed to find the area under a curve is integral calculus. The integral of the normal probability density function between the two points x 1 and x 2 is the area under the curve between these two points and is the probability … WebbThis statistics video tutorial provides a basic introduction into standard normal distributions.
