Solution:-
a) The name of the statistical test is one way Anova test.
b) The variable for the experiment is people sexual activity and different seasons.
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: u1 = u2 = u3 = u4
Alternative hypothesis: At-least one of the u is not equal.
e) Formulate an analysis plan. For this analysis, the significance level is 0.05.
Analyse sample data.
F statistics is given by:-
c) F = 5.00
Fcritical = 3.0725
d)
DFBetween = 3
DFWithin = 21
DFTotal = 24
f) Interpret results. Since the F-value (5.0) is greater than the significance level (3.07), we have to reject the null hypothesis.
Conclusion:-
Reject H0, There is sufficient evidence for significant differences between sexual activities of different seasons.
How do you write up an interpretation of the results ? I already filled out the...
A psychologist would like to know whether the season (fall, winter, spring and summer) has any consistent effect on people’s sexual activity. In the middle of eachseason he selected a random sample of n= 25 students. Each individual is given a sexual activity questionnaire. A one- factor ANOVA was used to analyze these data. Complete the following ANOVA summary table (a=0.05) Source SS df MS F Crit value Between 5.00 Within 960 Total Part A: Complete the ANOVA Summary table...

All work must be shown. That is, you need to show the steps and calculations you used to arrive at every answer for credit - For example, I need to see which two numbers you divided to arrive at a particular S? value, F-ratio value, etc. The "Pygmalion Effect" refers to the effect of teacher expectations on student academic achievement and performance (for the classic study on this phenomenon, see Rosenthal & Jacobson, 1968; for a more recent review of...

Hi i will give you a thumbs up if you do this problem correctly. Sorting Analysis Code and Essay Due: 4/22/2019(Monday) Introduction And now for something completely different. Different sorting algorithms are better for different size data sets. Other sorting algorithms are better for data sets of a specific type – for instance, data that is already ordered. In this assignment you will implement four different sorting algorithms and collect statistics for each of those algorithms while sorting multiple different...
