Explanation Given Information: The data 10 , 12 , 12 , 8 , 30 , 12 , 8 , 10 , 5 , 23 . Formula used: The formula for standard deviation is defined as, s = ∑ ( x − x ¯ ) 2 n − 1 Here, x ¯ is the mean and n is the number of observations. Calculation: Consider the provided set of data. 10 , 12 , 12 , 8 , 30 , 12 , 8 , 10 , 5 , 23 To calculate the standard deviation, first calculate the mean of the data set. x ¯ = 10 + 12 + 12 + 8 + 30 + 12 + 8 + 10 + 5 + 23 10 = 130 10 = 13 Thus, the mean of the data set is obtained as 13 . Form a table to show calculations. x x − x ¯ ( x − x ¯ ) 2 10 − 3 9 12 − 1 1 12 − 1 1 8 − 5

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

(b) Let I[y] be a functional of y(x) defined by [[y] = √(x²y' + 2xyy' + 2xy + y²) dr, subject to boundary conditions y(0) = 0, y(1) = 1. State the Euler-Lagrange equation for finding extreme values of I [y] for this prob- lem. Explain why the function y(x) = x is an extremal, and for this function, show that I = 2. Without doing further calculations, give the values of I for the functions y(x) = x² and y(x) = x³.
