What effect on power will more alternatives have?
Question 48 options:
It will decrease power
Alternatives have no effect on power
It will cause power to continuously fluctuate (unstable)
It will increase power
Question 49 (1 point)
Two individuals are often in conflict in your workplace: Person
A who is 22 years old and Person B who is 63 years old. How could
you potentially categorize the source of their conflict?
Question 49 options:
Interdependence
There is no source
Differentiation...
alpha value is 0.05 if it is not specified in the problem.
**Everything should be in r code base.
4. Back to the iris dataset one last time! We wish to estimate
the probability of a flower’s species based on the available
measurements.
a. Build a Multinomial model to predict Species based on
Sepal.Length. Use it to estimate the probability of each species
for a flower with a sepal 6.3 cm long.
b. Build a Multinomial model to predict Species...
At an alpha level of 0.05, test to determine if the means of the
three populations are equal. The data below is based on samples
taken from three populations. Sample 1 Sample 2 Sample 3 60 84 60
78 78 57 72 93 69 66 81 66
Assume that you plan to use a significance level of alpha = 0.05
to test the claim that p1 = p2. Use the given sample sizes and
numbers of successes to find the z test statistic for the
hypothesis test.
A report on the nightly news broadcast stated that 10 out of 108
households with pet dogs were burglarized and 20 out of 208 without
pet dogs were burglarized.
Produce the following for each problem:
Assuming an Alpha = 0.05, calculate the number of replications
necessary for each factor (including interactions), to have a type
II error less or equal to 0.1.
Evaluate results and provide conclusion(s).
Scan the solutions to these problems.

I have calculated a probability of type two error at alpha 0.1
as 0.05730834612602564 and 0.05 as 0.11282997108101914. From these
values how would i conclude the sampling method is good enough to
reduce the effort(in my problem statement)
How should i interpret the value of chi square test, where the
result is
statistic=15.066337549525954, pvalue=0.019746985983350823
Use the following data to conduct a one-sample t test (
with alpha= 0.05) to determine if the score on a standardized test
( for scores that a are normally distributed) with a known
population mean of 100 is influenced by a new instructional
method:
95, 105, 110. 90, 120, 110, 100, 95, 105, 125, 80, 100, 120,
115, 115, 120, 120, 105.
Suppose you are performing a test of independence for 2
categorical variables with alpha=0.05. The row variable has 4
categories and the column variable has 5 categories. What is the
critical value?
1. drawn bell shaped curved showing rejected/ non rejection with an alpha value of 0.05
2. determine regression of the line equation y=bx+a
3. Find a and b
4. let 20 be x and what it indicated
5. Then set it up for 95% prediction interval

Use alpha = 0.05 for hypothesis testing unless specified
otherwise.
2. A college teacher decided to do an experiment to see whether
the position her students satin the classroom had an effect on
their performance in the class. At the beginning of the semester,
she randomly assigned each student to one of three classroom
positions: Front,Middle, or Back. As it turned out, 10 students
were assigned to the Front of the room, 14students to the Middle,
and 10 to the...
