The overall average score on a test of Emotional Intelligence is
50 for the general population. A member of the
admissions committee for the Ph.D. program in clinical psychology
at OU wants to know whether applicants to the program are higher in
Emotional Intelligence than the general
population. Twenty-five applicants were randomly
selected from the applicant pool and were given the Emotional
Intelligence test. The applicants’ mean score was 60
with a standard deviation of 10. Use an alpha level
equal to 0.01 to determine whether the applicants scored higher on
the Emotional Intelligence test.
a. Write the null and alternative hypotheses in words. (2 points)
Q8: Null in Words
Q9: Alternative in Words
b. Write the null and alternative hypotheses in symbols. (1 point)
Q10: Both null and alternative in symbols

Answer #1
Null hypothesis in words: The overall average score on the test of Emotional Intelligence is equal to 50 for the general population.
Alternative hypothesis in words: The overall average score on the test of Emotional Intelligence is greater than 50 for the general population.
Null hypothesis in symbol, H0: μ = 50
Alternative hypothesis in symbol, H1: μ > 50

With your newly-developed statistical tools, you decide
to put this hypothesis to the test. You know that the standard
intelligence quotient (IQ) score has a population mean of 100 with
a standard deviation of 15. You find that a random sample of 121
Lakers fans has an average IQ score of 103. Use this evidence to
test your roommate’s argument that Lakers fans are more intelligent
than the general population.

A researcher wants to
determine whether high school students who attend an SAT
preparation course score significantly different on the SAT than
students who do not attend the preparation course. For those who do
not attend the course, the population mean is 1050 (? = 1050). The
16 students who attend the preparation course average 1150 on the
SAT, with a sample standard deviation of 300. On the basis of these
data, can the researcher conclude that the preparation course...

In the population, IQ scores are normally distributed with a
mean of 100. A charter school wants to know if their students have
an IQ that is higher than the population mean. They take a random
sample of 15 students and find that they have a mean IQ of 109 with
a sample standard deviation of 20. Test at 1% significance level
whether the average IQ score in this school is higher than the
population mean.

You think that your class might be happier than the general
population. You want to conduct a hypothesis test to see if you are
right. Thus, you randomly sample 9 students in your class and find
that they have a mean happiness score of 3.25, with a standard
deviation of 1. You know information about the population
distribution. First, you know the population scores are normally
distributed. You also know that the mean happiness score for the
population from which...

A sample of five third-graders took a reading test. They then
participated in a reading improvement program, and took the test
again to determine whether their reading ability had improved.
Following are the test scores for each of the students both before
and after the program. You want to see whether the mean reading
score increased after the program.
After: 67 68 78 75 84
Before: 59 63 81 74 78

1) The value of the z-score that is obtained for a
hypothesis test is influenced by several factors. Some factors
influence the size of the numerator of the z-score and other
factors influence the size of the standard error in the
denominator. For each of the following, indicate whether the factor
influences the numerator or denominator of the z-score and
determine whether the effect would be to increase the value of z
(farther from zero) or decrease the value of...

A political scientist hypothesizes that a political ad will
reduce attitudes about a particular issue. The scientist randomly
asks 31 individuals walking by to see the ad and then take a quiz
on the issue. The general public that knows little to nothing about
the issue, on average, scores 50 on the quiz. The individuals that
saw the ad scored an average of 53.59 with a variance of 25.70.
What can the political scientist conclude with an α of 0.05?...
