Champagne is best when the bubbles are concentrated in the wine. A group of scientists compared gentle and splashing pouring methods for champagne by measuring the amount of bubbles in each glass of champagne poured two different ways at three different temperatures. The following data present the pattern of results obtained in the study. Chane of temperature

40 46 52
Gentle pour n=10 n=10 n=10
M=7 M=3 M=2
SS=64 SS=57 SS=47

Splashing pour n=10 n=10 n=10
M=5 M=1 M=0
SS=56 SS=54 SS=46

Required:
a. Use a two-factor ANOVA with α= 0.05 to evaluate the mean differences.
b. Briefly explain how temperature and pouring influence the bubbles in champagne according to this pattern of results.

Step-by-step explanation:

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
