The average annual wind speed in Rochester, Minnesota is 13.1 miles per hour. If a sample of 100 days was used to determine the average wind speed, find the 98% confidence interval of the mean. Assume the population standard deviation was 2.8 miles per hour.
Z D/2 = 2.33

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
