Examine the Variables: Carefully review and note the names of all variables in the dataset. Examples of these variables include: Mileage (mpg) Number of Cylinders (cyl) Displacement (disp) Horsepower (hp) Research: Google to understand these variables. Statistical Analysis: Select mpg variable, and perform the following statistical tests. Once you are done with these tests using mpg variable, repeat the same with hp Mean Median First Quartile (Q1) Second Quartile (Q2) Third Quartile (Q3) Fourth Quartile (Q4) 10th Percentile 70th Percentile Skewness Kurtosis Document Your Results: In RStudio: Before running each statistical test, provide a heading in the format shown at the bottom. “# Mean of mileage – Your name’s command” In Microsoft Word: Once you've completed all tests, take a screenshot of your results in RStudio and paste it into a Microsoft Word document. Make sure that snapshots are very clear. You will need multiple snapshots. Also transfer these results to the…

Using the linear correlation coefficient given above, calculate and give the value of the coefficient of determination. Explain in a sentence what this means in the context of this example, treating gpa as a predictor.

Please do not give solution in image format thanku Load "diabetes" datasets from SKlearn and do the PCA for n=3, and plot the data.   1. What is the variance (%) covered by the first 3 components? How is this percentage of variance computed?   2. Is there any correlation between these three components?   3. Apply t-SNE on the same dataset, select the first 3 components and plot them.   4. Report the comparison between the results obtained using t-SNE and PC

Which statistic would best describe the variable diastolic blood pressure (listed in mmHg) in your sample?     Frequency     Median     Mean     Variance

The data screening for the ANOVA involves:     examining the histogram for the independent variable     examining the scatterplot for the dependent variable     examining the histogram for the dependent variable     examining the scatterplot for the independent variable

Which bivariate data are most likely positively associated? The height and weight of a person The height above sea level and temperature

A researcher wants to determine if there is a relationship between number of classes students are enrolled in (1,2,3,4,5,etcc.) and stress level scores (measured on a multi-item Likert scale). What type of statistical test should be used?  Group of answer choices Correlation Analysis Chi Square Dependent t-test Independent t-test ANOVA

Determine the critical r values and if the correlation is significant

Help me slove the last two

Can you make a  histogram Graph for me  I just need it in histogram graph form? I need a graph for my class due this week? Thanks again  find the coefficient of a variance of the two samples: then compare the variation. Blood pressure measurements taken from data set 1 " the body data in appendix B and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurements. (use Ti for finding SD and mean) Systolic 118 128 158 96 156 122 116 136 126 120 Diastolic 80 76 74 52 90 88 58 64 72 82

Determine if the given subject is population or sample, then describe the given quantity as parameter or statistic
