Answer by solver91311 24713 Show Source. With a mean of 70 and a standard deviation of 5 a score of 80 is two standard deviations above the mean. Use the mean function to confirm that your array actually has a mean of 80. Assume the random variable x is normally distributed with a mean of 80 and a standard deviation of 5.
If the mean μ is 80 and the standard deviation σ is 5 then all scores between 80 and 90 would fall between 0 and 2 standard deviations above the mean. Use the std function to confirm that your standard deviation is 235. If X Is A Normal Random Variable With Mean 80 And Standard Deviation 5 The Z-score For X 88 Is A 18 B-18 C 16 D -16 E 80 This problem has been solved.

When the elements in a series are more isolated from the mean then the standard deviation. Consider the data value 80. A if a data set has mean 70 and standard deviation 5 is 80 a suspect outlier. Find the probability of x.
Around 68 of values are within 1 standard deviation of the mean. 5 A 826 B 835 C 765 D 774. 5 An aptitude test has a mean score of 80 and a standard deviation of 5. BLet z be a normal random variable with mean 0 and standard deviation 1.
Sketch the graph shade the appropriate area in the curve. In mathematical notation these facts can be expressed as follows where Χ is an observation from a normally distributed random variable μ is the mean. 8 - 4625. That means that only 455 of the data lies above 2 SDs above the mean.
Standard deviation denoted by the symbol σ describes the square root of the mean of the squares of all the values of a series derived from the arithmetic mean which is also called as the root-mean-square deviation. Sara scored an 88 on the first but only a 65 on the second. Using the equation for Z score Z X-μσ for each X value 80 and 90 then the Z scores are 0 and 2 respectively. If X is a normal random variable with mean 80 and standard deviation 5 calculate the z score if x 92.
