## Determine the area under the standard normal curve that lies to the left of the following z score. Use a table?

Can someone help me with these questions? I would like it if someone can explain how to find the answer on a Z table. I’m confused on how to read the table and get the answer. Thanks!!

Determine the area under the standard normal curve that lies to the left of the following z score. Use a table if necessary. Round your answer to four decimal places.

z = 0.33

Determine the area under the standard normal curve that lies to the right of the following z value:

z = 0.86

Use a table if necessary. Round your answer to the nearest ten thousandth.

Areas under Normal Distribution – Areas under portions of a normal distribution can be computed by using calculus. Since this is a non-mathematical treatment of statistics, we will rely on computer programs and tables to determine these areas. Figure 1 shows a normal distribution with a mean of 50 and a standard deviation of 10.Question: Find the area under the standard normal curve to the right of z = -1.81. Solution: To answer this question, we simply need to look up the value in the z table In the previous examples, we found that the area to the left of z = -1.81 was .0351 and the area to the left of z = 1.26 was .8962.Normal Distribution calculator calculates the area under a bell curve and gives the probability which is higher or lower than any arbitrary $X$. Enter the population mean, the standard deviation of the population and two value $X_1$ and $X_2$ in the box. These values must be real numbers.

How to Find the Indicated Area Under the Standard Normal Curve – what percentage of area under the normal curve lies between u-2o and u+2o. what is the area of a standard normal distribution curve to the left of z=0? less than 0.5.Finding the area under the standard Normal curve. Finding Areas Using the Standard Normal Table (for tables that give the area to left of z).Determine the area under the standard normal curve that lies between: Discussion in 'Calculator Requests' started by math_celebrity, Jan 8, 2017.

Normal Distribution Calculator – Given a standard normal distribution, how can I find the area under the curve that lies: 1. to the left of z = −1.39 edit1: most charts will give the area to the left of a given $z$-score. To find other values, use symmetry and complements. For example…Curve. (a) The Area To The Left Of Z-0.68 Is (Round To Four Decimal Places As Needed.) Solution : We have to determine area under the Standard Normal Curve that lies to the left of Click the icon to view a table of areas under the normal curve. (a) The area to the left of Z-0.68 is…In other words, find the Z-score such that the area under the standard normal curve to the left is 0.60. b. How many standard deviations above the mean is the 60th percentile? c. What proportion of combined GRE scores can be expected to be between 155 and 160? d. What is the probability that a…
