There are 1000 instances in the data set,
400 of them are Professor = Kimmer
and 600 of them are have deposition = mean
300 instances have both professor=Kimmer and deposition = mean
A)
the confidence of the rule " the professor = Kimmer then deposition is mean is given by "
B)
the support of the consequent deposition= mean is given by,
We have a dataset where we're considering the rule "if Professor Kimmer then Disposition- Mean". ...
Here is the link to the dataset --> https://ndh802.cfda.se/50591.txt is this answer correct? this was done in Studio? 1. What is the mean and sd salaries per males and females? 2. What is the t-statistic and the p-value of your test? 3. Do you reject the null hypothesis that males and females have equal salaries on average? 4. Finally, what is your answer - is there a gender wage gap in Sweden? Comment both the statistical and the economical signifcance...
Using the RateMy Professor (Rateprof) dataset from alr4, we will explore the process of the stepwise method quality is the response variable. gender, numYears, numRaters, numCourses, pepper, discipline, dept, helpfulness, clarity, easiness, raterInterest are the predictor variables. For simplicity, interactions are not considered. To understand the meaning of the variables, please use the code ?Rateprof after you import the library alr4. Consider quality ~1 to be the simplest model under consideration, and quality~ 1 + gender+ numYears+numRaters+ numCourse s +...
Assume that we have three independent observations: where Xi ~ Binomial(n 7,p) for i E { 1.2.3). The value of p E (0, 1) is not known. When we have observations like this from different, independent ran- dom variables, we can find joint probabilities by multiplying together th ndividual probabilities. For example This should remind you the discussion on statistical independence of random variables that can be found in the course book (see page 22) Answer the following questions a...
Working on practice scenarios for an upcoming exam. Question 2) A professor wants to find our if premature exposure to grade school will have an affect on IQ. She gathers 24 kindergarten aged children. One group of them is placed into grade school for 2years and the other group remains at home with their families. After the conclusion of 2 years, the IQs are measured. Assume alpha .01 ONE tail Each part is worth 2 points, answer all parts correctly...
1) Independence is often defined as p(x,y) = p(x)p(y). Using thedefinition of conditional probability p(x|y) = p(x,y)/p(y), show thatthe alternate definition p(x|y) = p(x) must be true if p(x,y) = p(x)p(y).For the following problem please don't round your answers until thefinal step, and SHOW ALL STEPS IN YOUR CALCULATIONS!)2) Congratulations! You've been accepted into Hogwarts' School ofWitchcraft and Wizardry. As you step into the Great Hall, you see arow of students waiting for the Sorting hat to tell them what...
what does manipulated varible mean? what does responding varible mean? what does hypothisis mean? In an experiment, a manipulated variable is one that can be easily changed by the xperimenter, such as the length of a pendulum The responding variable will be something that is the measured response to the change, such as the period of oscillation of a pendulum A summary of experimental terms might be helpful. An independent/manipulated variable is the potential stimulus or cause, usually directly manipulated...

2. Suppose we have a Normal distribution with mean 35 and standard deviation 4. Take a few a. minutes to draw this curve very neatly and accurately. Reference the document "How to Draw a Normal Curve" in this assessment. Use a separate sheet of paper, or add extra space here, and use a straightedge to draw an axis. b. Label your curve from part a with the 68-95-99.7 Rule. c. If we randomly select a value from this Normal model...
1. One of the calculations we do this week is the “expected value” or mean of a distribution. a. In your non-math life, what does “expected” mean to you? Answer in 1 – 5 complete sentences. b. What does “expected value” mean in a probability/statistics situation? How is it calculated? Answer in complete sentences, please (not math; use words). 2. Suppose we have a Normal distribution with mean 35 and standard deviation 4. a. Take a few minutes to draw...
I have a question about Henry II. What did he do that solidified his power as king but led to economic problems and helped incite conflict with the church.The possible answers are:Executed all Bishops who were opposed to his ruleGave enormous finiacial gifts to the nobility to gain their support in his conflict Built and rebuilt castles througout the landAll of themI researched through every possible site and I know for sure he destroyed castles and rebuilt especially Dover Castle...
