Yield vs temperature. This data set of size
n = 15 (Yield.csv) contains measurements of yield from an
experiment done at five different temperature levels. The variables
are y = yield and x = temperature in degrees
Fahrenheit. The table below gives the data used for this analysis.
Fit a simple linear model, a quadratic regression model, a cubic
regression model, respectively. Which one do you choose as the
final model? List your justifications.

What is the rank correlation coefficient? (Round to
three decimal places.)
What is the critical rho value at a 0.01 significance?
Do we have correlation?
Yes, the rank correlation coefficient is larger (in absolute
value) than the critical rho value.
No, the rank correlation coefficient is smaller (in...

We wish to determine the impact of Specification Buying, X11, on
Satisfaction Level, X10. To do so we will split the Hatco data file
into two separate data sets based on the Specification Buying, X11.
This variable has two categories:
1=employs total value analysis approach, evaluating each
purchase separately;
0 = use of specification buying.
Sort the entire Hatco data set based on Specification Buying.
This will create two separate groups of records. Those records with
X11 = 0 and...

Given the data set with t values in the first column and y
values in the second column, write a script file that:
-Curve fits the given data set with an appropriate polynomial
function
-Outputs the R2 value of the appropriate fit along
with the values of the polynomial order higher and lower (ex. If
you choose a 2nd order fit, display the R2
value for first, second, and third order fits.)

The American Association of Individual Investors (AAII) On-Line
Discount Broker Survey polls members on their experiences with
discount brokers. As part of the survey, members were asked to rate
the quality of the speed of execution with their broker as well as
provide an overall satisfaction rating for electronic trades.
Possible responses (scores) were no opinion (0), unsatisfied (1),
somewhat satisfied (2), satisfied (3), and very satisfied (4). For
each broker summary scores were computed by calculating a weighted
average...

Problem Set 2: Pearson’s correlation (7
pts)
Research Scenario: Is there a positive
relationship between grit and GPA in high school seniors? A
researcher examined this issue by having students beginning their
senior year of high school complete a grit inventory using a
Likert-based scale (range 1 – 7), where higher numbers indicate
more “grit”. GPA was self-reported (scale 0 – 4.0). Enter the data
shown here into SPSS to assess whether there is a positive
relationship between grit and...
