Analysis of the oil data set. One project from Fall 1999 consisted of heating motor oil until it catches on fire. There were eight runs in random order where "conv" stands for conventional oil, "syn" stands for synthetic oil, "5/30" and "20/50" are two viscosities, and "time" is the time until catching fire. The data are as follows>> viewdata(oil)Obs type vis time 1 conv 5/30 345 2 syn 5/30 658 3 conv 20/50 360 4 syn 20/50 546 5 conv 5/30 360 6 syn 5/30 676 7 conv 20/50 342 8 syn 20/50 512Run lm in Splus or M-Lab to get the ANOVA output for determining (use full model: model time=vis+type+vis*type, after class vis type)a) if there is mean difference in oil types (conv vs. syn): p value =b) if there is mean difference in viscosity levels (5/30 vs. 20/50): p value =c) and an interaction between the factors: p value =

Step-by-step explanation:

We shall analyse this in the open source statistical packageR , the complete R snippet is as follows

# read the data into R dataframe

data.df<- read.csv("C:\\Users\\586645\\Downloads\\Chegg\\syn.csv",header=TRUE)

str(data.df)

# perform anova analysis

a<- aov(lm(time~type*vis,data=data.df))

#summarise the results

summary(a)

colr<-c("salmon3" , "plum2","coral1","palegreen1" ,"orangered" ,"magenta4" )

# plots

boxplot(time~type*vis, data=data.df,ylab="Values",

main="Boxplots of the Data",col=colr,horizontal=TRUE)

attach(data.df)

interaction.plot(type,vis,time, type="b", col=c(2:6),

leg.bty="o", leg.bg="beige", lwd=2, pch=c(18,24,22),  

xlab="Type",

ylab="Value",

main="Interaction Plot")

The results are

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
