Use the following data (in the table) to answer questions. The Yum-Yum Chocolate Co. is in the processes of manufacturing a new thermo-tolerant chocolate. That is chocolate that can withstand higher temperatures and resist melting, plus taste great! Three recipes have been developed by R&D, and the researchers are interested in which chocolate recipe has the highest average heat tolerance. Below are the results from the heat tests for each chocolate recipe. All elements of the experiment were held constant, and the melting points (heat tolerances) were recorded as follows: Melting Points in Degrees Celsius
Chocolate AChocolate BChocolate C
373237
353138
323334
363436

Consider a completely randomized design.
a) What is/are the factors in the problem?
b) What are the treatments/level for the factors?
c) How many replicates are made per treatment?
d) Are appropriate assumptions met in order to run the ANOVA?
e) At 5% significance, is there evidence of a difference between the average melting points for the 3 chocolate recipes?

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.

step-by-step explanation:

pretty sure 750 each month!

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
