Create a matrixwith 4 rows and 8 columns with every element equal to 0. Create a second, smallermatrix with 2 rows and 4 columns where each row is [1234]. Replace the 0s in the upper left-hand corner of the biggermatrix with the values from the smaller matrix. (If you do this correctly, the first 4 columns of the first 2 rows of the big matrix will change.) Display the modified big matrix.

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?
