Please kind i get a professional to help me with my homework questions on Statistic.

Homework 5

----------

Do the following problems from the textbook (see notes below!):

6.2, 6.5(a,b,d), 6.6(a,b), 6.7(a), 6.8,

6.18(c,e), 6.19(a,c), 6.22(a, c), 6.23(a),

3.3(c,d), 3.6(b,c), 3.16(a, c, d, e, f).

NOTE: Problems 6.5, 6.6, 6.7, 6.8, 6.18, 6.19,

3.3, 3.3, and 3.16 require analysis using a

computer package such as SAS or R.

NOTE: For 6.5(a) use pairs(brand) and cor(brand) in R

NOTE: For 6.5(d) and 6.18(e), you only need to do the

residual plot of the residuals against the predicted

values, Y-hat (i.e., the type of plot we did an

example of in class). You may optionally do the plots

of the residuals against the other terms the book

mentions.

NOTE: For 6.8, interpret both the confidence interval and the prediction interval.

NOTE: For 6.23(a), will be counted as a 5 point bonus added to Exam 1. Do NOT use any resources but your notes and the textbook.

NOTE: For 3.16(c), note that the function for base-10

logarithms is log10( ), both in SAS and in R.

The "Brand Preference", "Commercial Properties",

and "Solution Concentration" data sets are

given on D2L.
