Question

Question 1:

a) what experimental design approaches are used to prevent

pseudoreplication.

b) If, after the research is completed, the researcher obtains a
p-value of 0.06 What does this p- value signify? What should they
do? Is there a way to salvage this experiment?

c) What does it mean when we say that a result is ‘statistically
significant’?

please explain it briefly

Answer #1

(a) To prevent pseudoreplication, the following experimental design approaches are used generally-

- We have to properly extrapolate the Sample Size.
- We have to draw up a sampling frame for the primary sampling unit.
- The response variable measurement with sufficient precision within each primary unit.
- We must analyse the data using the average value for each unit.

(b) After a research, if researcher obtains p-value of 0.06, it means probability of obtaining the result under the null hypothesis is 6%. if p value is greater than 0.05, it is not statistically significant.

(c) When the null hypothesis is true, if there is a low probability of getting a large result, it is called "statistically significant".Generally p value less than 0.05 is statistically significant.

In a completely randomized design, 10 experimental units were
used for the first treatment, 12 for the second treatment, and 19
for the third treatment. Sum of Squares due to Treatments and Sum
of Squares Total is computed as 1100 and 1700 respectively. Prepare
the ANOVA table and complete the same (fill out all the cells).
State the Hypotheses. At a .05 level of significance, is there a
significant difference between the treatments? Use both p-Value and
Critical-Value approaches.

The null hypothesis is there will be no difference in the
frequency of graduates who are employed in residential treatment
facilities, community agencies, and private practice. The
researcher used a Chi-Square Goodness of Fit test to analyze the
data.
The expected frequency for each category of employment is 33.3%.
The raw data on frequencies is:

Question 6 (1 point)
The federal government recently granted funds for a special
program designed to reduce crime in high-crime areas. A study of
the results of the program in high-crime areas of Miami, Florida,
are being examined to test the effectiveness of the program. The
difference in crimes reported is calculated as (crimes after -
crimes before). You want to test whether the average number of
crimes reported after are greater than the average number of crimes
reported before....

Question 11 (1 point)
A comparison between a major sporting goods chain and a
specialty runners' store was done to find who had lower prices on
running shoes. A sample of 34 different shoes was priced (in
dollars) at both stores. To test whether the average difference is
less than zero, the hypotheses are as follows: Null Hypothesis:
μD ≥ 0, Alternative Hypothesis: μD < 0. If
the average difference between the two stores (specialty -...

A suggestion is made that the proportion of people who have food
allergies and/or sensitivities is 0.48. You believe that the
proportion is actually less than 0.48. The hypotheses for this test
are Null Hypothesis: p ≥ 0.48, Alternative Hypothesis: p < 0.48.
If you select a random sample of 28 people and 12 have a food
allergy and/or sensitivity, what is your test statistic and
p-value?

Question 12 (1 point)
A medical researcher wants to determine if the average hospital
stay of patients that undergo a certain procedure is greater than
8.7 days. The hypotheses for this scenario are as follows: Null
Hypothesis: μ ≤ 8.7, Alternative Hypothesis: μ > 8.7. If the
researcher takes a random sample of patients and calculates a
p-value of 0.0942 based on the data, what is the appropriate
conclusion? Conclude at the 5% level of significance....
