Use the data from question 1. Conduct a hypothesis test at α =
.01 to determine if the population variance is greater than
904.75.
Question 1: 1. Consider the following sampled data: s 2 =
906.304, n = 31. Calculate the following confidence intervals for
the population variance: (a) 90% (b) 95% (c) 99%

Test at α =.05 the hypothesis that a majority (more than 50%) of
students favor the plus/minus grading system at a university if in
a random sample of 400 students, 216 favor the system?

Using the SATGPA data set in Stat2Data package. Test by using α=
.05.
1) Create the following three variables and then print out all
the six variables.
Create a new variable “SAT”, which is the sum of MathSAT and
VerbalSAT.
Create second new variable “SATLevel”, and assign the value of
“SATLevel” as 1 when
SAT<=1100, 2 when
1100<SAT<=1200, 3 when 1200<SAT<=1300, and 4 when
SAT>1300.
Create third new variable “GPALevel” and assign the value of
“GPALevel” as 1 when
GPA<=2.8,...

Please conduct an independent-sample t-test, α =
.05.
Two persons are arguing about the size of different breeds of
dogs. One believes that German Shepherds are larger than Huskies,
while the other person believes the opposite is true. So they
conducted a study to see which one of them is correct by randomly
sampling and weighting 10 dogs of each breed they saw on a Sunday
afternoon in their community. This is an independent-sample case.
The data are as follows:...
