Calculate the sample standard deviation and sample variance for the following frequency distribution of final exam scores in a statistics class. if necessary, round to one more decimal place than the largest number of decimal places given in the data. final exam scoresclassfrequency56 - 641165 - 731574 - 821483 - 91492 - 10011

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
