1.Create a new variable WHISCO that tells us the liking for whiskey and scotch combined. What is the mean of this new variable? 3.3581

2.What is the mean liking for regular beer for the females that

completed the survey? 3.0571

3.Create a new variable HARD that tells us the liking for whiskey, gin, rum and scotch combined. What is the mean of this new variable?3.7703

4.What is the mean liking for whiskey for the males that completed the
survey?4.7105

---------------------------------------------------------------------------------------------------------------------------- The following two statements are Null Hypotheses written in English. For each, rewrite the null using mathematical symbols and notation as shown in the ClassPak. The statement in parentheses refers to the Alternative Hypothesis for each.

5. On average IU students go out 2.5 nights or more per week. (The alternative hypothesis is that IU students go out less than 2.5 times per week.)

Ho: μNights >= 2.5
Ha: μNights < 2.5

6. On average IU students drink exactly 5 1/2 drinks in an average night out. (The alternative hypothesis is that IU students do not drink 5 1/2 drinks per night out.)

Ho: μDrinks = 5.5
Ha: μDrinks ≠ 5.5

Use SPSS to calculate a p-value for each of the null hypotheses you have written in 5 and 6 above:

...I am the Statistical Analyst for Slivers’ Gold Gym (SGG). I was assigned a project to examine the relation of 252 male gym members weight and body fat by conducting a hypothesis test. This report reflects the measures that I examined and how I conducted my hypothesis test to conclude if the male members have an average body fat of 20% as claimed by my boss.
Part I
I analyzed the compiled sample data set that was provided to me for the hypothesis test of the body fat and...

...following information is for Questions 9 and 10.
The tête-à-tête between MSF and AFP broke down, as anyone would have anticipated. They are going to court.
The presiding judge, His Honor Ig Sushi, is rather apprehensive of errors in any statistical testing. Let us assume he picks a 95% significance level, an industrial standard, to be the benchmark of this court case.
I know, I know, everything sounds rather fishy......

...Hypothesis Testing For a Population Mean
The Idea of Hypothesis Testing
Suppose we want to show that only children have an average higher cholesterol level than the national average. It is known that the mean cholesterol level for all Americans is 190. Construct the relevant hypothesis test:
H0: = 190
H1: > 190
We test 100 only children and find that
x = 198
and suppose we know the population standard deviation
= 15.
Do we have...

...Simple Hypothesis: A statistical hypothesis which specifies the population completely (i.e. the form of probability distribution and all parameters are known) is called a simple hypothesis.
1. Composite Hypothesis: A statistical hypothesis which does not specify the population completely (i.e. either the form of probability distribution or some parameters remain unknown) is called a Composite Hypothesis.
Hypothesis Testing or Test of Hypothesis or Test of...

...Kruskal-Wallis Tests in SPSS
STAT 314
Three teaching methods were tested on a group of 19 students with homogeneous backgrounds in statistics and comparable aptitudes. Each student was randomly assigned to a method and at the end of a 6-week program was given a standardized exam. Because of classroom space and group size, the students were not equally allocated to each method. The results are shown in the table below. Test for a difference in distributions (medians) of the test scores...

...EXERCISE 36 Questions to be graded
1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619,p = 0.005. Discuss each aspect of these results.
Answer
F-value shows significance between the two groups. The null hypothesis should be rejected because the P-Value is 0.005 which would mean that the groups are different.
2. State the null...

...study of 2,000 shots by a single
player is analyzed. For this player, the model of Bernoulli trials is inadequate.
KEY WORDS: Bernoulli trials, the hot-hand, power, simulation study, case study.

1 Introduction
In this paper I consider a statistical analysis of basketball shooting in a controlled (practice) setting, with
special interest in the hot-hand. In Section 2, I review and critically examine the two seminal papers on this
topic: Gilovich, Vallone, and...

Due: Sunday, May 19 (by 8am).
1. a) In Chapter 6, you learned to find interval estimates for two population parameters, a population mean and a population proportion. Explain the meaning of an interval estimate of a population parameter.
An interval estimate for a specified population parameter (such as a mean or proportion) is a range of values in which the parameter is estimated to lie. In...
