2) Use the data in the table to answer the question. The x-values are amounts of saturated fat 2) (in grams) in various regular two-ounce muffins. The y-values are amounts of saturated fat (in grams) in various "low fat" two-ounce muffins. Amounts of Saturated Fat in Regular and Low-Fat Muffins x 4.5 3.5 3.7 5.2 4.9 3.9 y 1.2 2.1 2.2 1.8 1.6 2.2 Note that the table lists measured amounts of saturated fat in two different types of muffin. Given these data, wha values? t issue can be addressed by conducting a statistical analysis of theExplanation / Answer
Statistical anlysics of using R Code:
----------------------------------------------------
#here x=amount of saturated fat in variours regular 2 ounce muffins.
#here y=amount of saturated fat in variours "low fat" 2 ounce muffins.
x=c(4.5,3.5,3.7,5.2,4.9,3.9)
y=c(1.2,2.1,2.2,1.8,1.6,2.2)

mean of amount of saturated fat in various regular 2 ounce muffins (x) is 4.283.
mean of amount of saturated fat in various "low fat" 2 ounce muffins (y) is 1.850. so saturated fat is so high in various regular 2 ounce muffins as compare to "low fat" 2 ounce muffins.
variance of amount of saturated fat in various regular 2 ounce muffins (x) is 0.4736667.
variance of amount of saturated fat in various "low fat" 2 ounce muffins (y) is 0.159 so there is less variability in "low fat" 2 ounce muffins as compare to regular 2 ounce muffins.
Cheers!
