real-world example and associate each part of your example with the
associated technical concepts.

Write down the null hypothesis.
Write down the alternative hypothesis.
Explain why you chose your hypotheses as such.
Do a hypothesist test of your data at the α = 2% level of
significance for the population proportion by carrying out the
following five steps:

If it is a left-tailed test, what is the critical value,

If it is a right-tailed test, what is the critical value,...
Create a null hypothesis and alternative hypothesis for a drug
company that claimed frequency of headaches were decreased in over
50% of migraine sufferers that participated in a study for a new
migraine medication. Describe the variable that would be tested and
what would be your guess of the value of that variable. Then
include how the result, if the null were rejected or not, might
change your conclusions or actions in some way.
What is a null hypothesis?
Wat is an alternative hypothesis?
Then articulate a null hypothesis and alternative hypothesis for
a research study that pertains to you're area of
specialization.
What conclusions can be drawn from this study with a
"statistically significant" result?
For each of the following studies, write a null hypothesis (Ho)
and an alternative hypothesis (Ha). For each part, also indicate
whether you have written a one-tailed or two-tailed alternative
hypothesis. a. An organizational psychologist examined whether an
office redesign would change employees’ satisfaction levels. b. A
forensic cognitive psychologist wondered whether repetition of
false information would increase the tendency to develop false
memories on average. c. A clinical psychologist studied whether
structured assessments of therapy would lead to a...

Null Hypothesis: There is no significant difference in the
housing expenses between married and unmarried households.
Alternative Hypothesis: There is a significant difference in the
housing expenses between married and unmarried households.
what are the type I and type II errors?
Write a null and alternative hypothesis for single sample that
tests the idea that the population mean is greater than or equals
25. Draw a sampling distribution which indicates the regions of
rejection.
