“About Us” Survey. Test hypothesis to check the claim that
gender doesn’t create any difference in heart rates between young
males and females. Use the significance level = 0.01 .
Use two random samples taken from survey data and computer output
provided.
Don’t need to calculate the standard error by hand, use SEx1 −x2
= 4.51
Fill out the table
Write appropriate null and alternative hypotheses.
Perform the test.
Estimate and interpret the p-value.

Use the Crosstabs option in the Descriptives menu to answer the
questions based on the following scenario. (Be sure to select
Chi-square from the Statistics submenu and Observed, Expected, Row,
and Column in the Cells submenu. Assume a level of significance of
.05) You are interested in determining the existence of a
significant interaction between three Preferred Instructional
Strategies and Gender. Two hundred students from three introductory
psychology classes were asked about their preferred instructional
strategy. The results are shown...

Chapter 11: Using the attached dataset “Chapter 11 Data Set 1”
to test the research hypothesis that males raise their hands in
class more often than females. (Please note that these data are not
exactly the data provided by the author). Is this a directional or
non-directional hypothesis? Should you use a one-tailed or
two-tailed test? What is the corresponding null hypothesis? Conduct
the between groups t-test using Excel (either method). Use the .05
confidence level. What is your conclusion...

The research hypothesis: The number of hours of TV watching
tends to vary by gender (sex) ( the greater the number represents
more hours). Alpha = .01
The date I used is GSS2010
1. Write out the null hypothesis and indicate whether this is a
one-tailed or two-tailed test; 2. get the t critical
value; 3. Make your decision whether we should reject the null
hypothesis based on the test results (i.e.
t(obtained), and p value).

Directional versus nondirectional hypothesis testing. Cho and
Abe (2013) provided a commentary on the appropriate use of
one-tailed and two-tailed tests in behavioral research. In their
discussion, they outlined the following hypothetical null and
alternative hypotheses to test a research hypothesis that males
self-disclose more than females:
H0: µmales − µfemales ≤ 0
H1: µmales − µfemales > 0
What type of test is set up with these hypotheses, a
directional test or a nondirectional test?
Do these hypotheses encompass...

Context:
Are males more likely to purchase fried products than females?
You record the gender of all the customers for one week and find
the following:
Purchased Fried Product
Did NOT Purchase Fried Product
Total
Male
42
33
75
Female
38
43
81
Total
80
76
156
At the 0.05 level of significance, is there evidence that there
is a difference in the distribution of sales of fried products
between males and females. Use Excel to calculate your answers

A researcher was interested in the relationship between
an average daily time spent on social media (i.e., X variable) and
social anxiety (i.e., Y variable).
The data collected on a sample of n =
82 undergraduate students produced the following
results: SSx=
49, SSY= 36, SP = 11,
MX = 8, MY =
15.
A. Is there a significant correlation between an average daily
time spent on social media and social anxiety? Use 2-tailed test,
p < .05 to answer this research...

content on social media and their gender?
In this study the feelings about
social media content investigated were: (a) anger, (b) inspiration,
