Based on longitudinal study of 98 randomly chosen people conducted during 1996, National Center for Cottage Cheese Studies found the average cottage cheese consumption of 2.75 pounds and the standard deviation of *s *= 14 ounces. Given this information, which of following statements would be *right *concerning a twotail test at 0.05 level of significance?

a)** **We can conclude that average cottage cheese consumption in America is at least 0.705 pound more or less than 2.75 pounds per person per year.

b)** **We can conclude that we cannot refuse claim that average cottage cheese consumption in America is 2.6 pounds per person per year.

c)** **We can conclude that average cottage cheese consumption in America is not 2.6 pounds per person per year.

d) We can conclude that average cottage cheese consumption in America is actually 2.75 pounds per person per year.
