Problem 18

Which way of dispensing champagne, the traditionalvertical method or a tilted beer-like pour, preserves moreof the tiny gas bubbles that improve flavor and aroma?The following data was reported in the article On theLosses of Dissolved CO2 during Champagne Serving(J. Agr. Food Chem., 2010: 87688775).Temp (C) Type of Pour n Mean (g/L) SD18 Traditional 4 4.0 .518 Slanted 4 3.7 .312 Traditional 4 3.3 .212 Slanted 4 2.0 .3Assume that the sampled distributions are normal.a. Carry out a test at significance level .01 to decidewhether true average CO2 loss at 18 C for the traditionalpour differs from that for the slanted pour.b. Repeat the test of hypotheses suggested in (a) for the12 temperature. Is the conclusion different from thatfor the 18 temperature? Note: The 12 result wasreported in the popular media.

9/13/16 Statistics 201: Probability and normal distribution  Random event­ something that may or may not occur, and that we can assign a probability to.  Examples: ­ a coin might fall on heads ­ tomorrow might snow ­ the broncos might win the super bowl ­ Gryffindor might win the house cup  Random variable­ “x” , i.e. the roll of a die  Complement­ is the nonoccurrence or opposite of an event.  Examples: ­ coin might fall on tails ­ tomorrow might not snow ­ broncos could lose the superbowl ­ Gryffindor might lose the house cup  Probability – quantifying the likelihood of a random event occurring, usually
