Nabico industry has two different production units to produce their popular biscuit, which comes in the package they claim to be 200gm. The line manager collected 40+a=.... samples from production unit 1 and 45+ß=... samples from production unit 2 for the analysis. The historical data shows that the average population weight and the standard deviation of product from unit 1 are 205-y=..... and 3gm respectively. However, for the samples from unit 2, these statistics are 198-8=.. and 2.5gm respectively. Based on the available data, calculate the probability that the difference in average weight between the product of unit 1 and unit 2: a. Exceeds 6 gm. b. Lies in between 5.0 gm to 7.0 gm. c. Assume that the population standard deviation in unit 2 is 6 gm (instead of 2.5gm) and the company will close unit 2 if the difference in the weight of product between unit 1 and unit 2 exceed 6.5 gm. Will the company close unit 2, provided that other statistics remain same? Justify your answer based on appropriate analysis. (3.0) (3.0) (3.0)

Nabico industry has two different production units to produce their popular biscuit, which
comes in the package they claim to be 200gm. The line manager collected 40+a=....
samples from production unit 1 and 45+ß=... samples from production unit 2 for the
analysis. The historical data shows that the average population weight and the standard
deviation of product from unit 1 are 205-y=..... and 3gm respectively. However, for the
samples from unit 2, these statistics are 198-8=.. and 2.5gm respectively. Based on the
available data, calculate the probability that the difference in average weight between the
product of unit 1 and unit 2:
a. Exceeds 6 gm.
b. Lies in between 5.0 gm to 7.0 gm.
c. Assume that the population standard deviation in unit 2 is 6 gm (instead of 2.5gm) and
the company will close unit 2 if the difference in the weight of product between unit 1
and unit 2 exceed 6.5 gm. Will the company close unit 2, provided that other statistics
remain same? Justify your answer based on appropriate analysis.
