Problem 7.4.44

In Exercises 3946, find the determinant of the matrix. Expand by cofactors using the indicated row or column. 7613002001316224 2 (a) Row 4 (b) Column 2

Step-by-Step Solution:
Step 1 of 3

● Population Variance ○ If N is the number of values in a population with mean mu, and xi represents each individual in the population, the the population variance is found by: ○ σ 2 = sumN i=1 (xi − µ) 2 N ○ and the population standard deviation is the square root, σ = √ σ 2. ○ Most of the time we are working with a sample instead of a population. So the sample variance is found by: s 2 = Pn i=1 (xi − x¯) 2 n − 1 and the sample standard deviation is the square root, s = √ s 2. Where n is the number of observations (samples), xi is the value for the i th observation and x¯ is the sample mean. ○ By hand ­ find mean, square each scores, 1/(#­
