Alcohol in wine. The alcohol content of wine depends on the grape variety, the way in which
the wine is produced from the grapes, the weather, and other influences. Here are data on the
percent of alcohol in wine produced from the same grape variety in the same year by 48
winemakers in the same region of Italy. It is known that the expected content should be 12%
a)
Plot each data set in Histogram to investigate the shape of the distributions and explain
the what you see. (Hint: Try using bin range of 0.25)
Explanation
b)
Set up the Null and Alternative Hypothesis (95% Confidence)
Null Hypothesis
Alternative Hypothesis
c)
What are the df (degrees of Freedom)?
d)
What is the p-value (Show you work on how you got it).
e)
Determine the Confidence Interval ay 95%.
f)
Based on your confidence interval, is the mean alcohol content significantly different at
the a = 0.05 level from 12%?
Explanation
g)
Based on your confidence interval, is the mean alcohol content significantly different at
the a = 0.05 level from 13%?
