a) Calculate the mean of the salaries of the 20 people. The Z-score tells the statistician how different a piece of data is from the average for the set. Median: 3437500 viii.) The Z-score measures how many standard deviations a figure is from the average. Which set has the largest standard deviation? 21)The scores on a mathematics exam have a mean of 77 and a standard deviation of 8. Consequently, it is called a sensitive measure because it will be influenced by outliers.

Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Suppose that the distribution of salaries is normal with a standard deviation of $7500. Example Let there be 2 companies A and B. Take square root of result SD is the square root of the average squared deviation from the mean 21 b.

The modulus of difference between both left & right side values is the probability of two tailed Z-score values.Here is the recipe for calculating it: Therefore, the critical (rejection region) value of Z on right side is 0.9878ДЇind the difference between left & right tail critical values of Z Similarly refer column value for -2.2 and row value for 0.05 in the positive values of standard normal distribution to find the right tail. Therefore, the critical (rejection region) value of Z on left side is 0.0418

Refer the column value for -1.7 and row value for 0.03 in the negative values of standard normal distribution to find the left tail.

1.73 < Z < 2.25 is the two tailed distribution. The point where the column & row values met at 0.0016 is the probability or critical value of Z. To find the probability of z-score, refer the column value for -2.9 and row value for 0.05 in the negative values of standard normal distribution. 2.95 < Z is the left tailed distribution. The point where the row & column meets for the corresponding z-score value is the critical value of Z or the rejection area of one or two tailed z-distribution. Refer the column & row values for z-score. Z-scores generally ranges from -3.99 to 0 on the left side and 0 to 3.99 on the right side of the mean. Supply the positive & negative values of the z-score to find the rejection region at both right and left side of the mean of normal distribution. Supply the positive or negative value of z-score to find the rejection region right or left to the mean of normal distribution respectively.

Users may use this one or two tailed z-table calculator or refer the rows & columns value of standard normal distribution table to find the critical region of z-distribution.ДЇor one one (left or right) tailed Z-test : Standard Normal Distribution Table for Z = -3.59 to 0.00 Standard Normal Distribution Table for Z = 0.00 to 3.59 It means that the negative z-score lies on left side represents the left tail & the positive score lies on right side represents right tail of the distribution. The negative & positive z-scores lies on the left & right side of the mean of standard normal distribution respectively.

This Z-table to find the critical value of Z is also available in pdf format too, users may download this table in pdf format to refer it later offline. For locating the Z e (critical value of Z) in the table quickly, users can supply the values of Z-score in the above interface.

The estimated value of Z or Z-statistic (Z 0) is compared to critical value of Z from standard normal-distribution table to check if the null hypothesis in the Z-test is accepted or rejected at a specified level of significance (О±).

Standard normal-distribution table & how to use instructions to find the critical value of Z at a stated level of significance (О±) for the test of hypothesis in statistics & probability surveys or experiments to large samples of normally distributed data.
