The mean of such variable is the expected value of variable Y, and the standard deviation is calculated as: σY=E(Y2)−(E(Y))2.Answer and Explanation: Given Information: The given values of gross profit (Y) and corresponding probabilities (P(Y)) are: Y 1 1.5 2 4 10 P(...

The program given below calculates the values of bar x and sigma. It uses array x of type float to store the given numbers (maximum 50) and variable n of type int to represent the number of elements in array x. Also, the variables sum, mean and sd (all of type float) are used to...

σ– The SD of the population studied. When using the formula, the mean and SD values will stay constant, only the score to be converted will be changed. Using the Z-score formula with an example So, let me use an example to demonstrate how to use the Z-score formula. Below is a ...
Use this standard deviation app to determine the standard deviation and variance with a single click. With the help of SD, you can easily find how close the sample mean is to the actual mean of the population. You can use this standard deviation calculator app for to generate absolute ...
and X ray was performed after 6 hours.Results: In our study, out of 320 cases, 201(62.81%) were between 1-15 days while 119(37.19%) were between 16-28 days of life, mean+sd was calculated as 13.58卤7.59 days, 187(58.44%) were male and 133(41.56%) were female, frequency of ...
Airway resistance was calculated using 6 methods: Suter, Krieger, Neergard, Bergman, Comroe, and Jonson.Results. Mean calculated resistances (± SD) (cm H2O/L/s) were 11.7 ± 4.8 (Suter method), 13.3 ± 5.0 (Krieger method), 14.9 ± 5.3 (Neergard method), 25.0 ± 6.6 (Bergman ...
Given a standardized normal distribution with mean = 0 and sd = 1, what is the probability that: A) Z is less than 1.57? B) Z is greater than 1.84? C) Z is between 1.57 and 1.84? D) Z is less than 1.57 or greater than 1.84? Find the probability ...
Calculate SD: σ = √Variance = √32.83 = 5.73Standard Deviation of Discrete Data by Assumed Mean MethodWhen the data values are very large, then one of the data values is chosen as the mean (and hence is known as assumed mean, A). Then the deviation of each data value from the ...
