Preliminary data analyses indicate that you can reasonably apply the z-interval procedure. find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. assume a population standard deviation of 190.0. note: the sum of the data is 8279.

The CI of the 'true mean= [455, 609]

Step-by-step explanation:

Please see attachment.

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
