Hi! I pretty much don't understand these problems that were presented on my Statistics class An engineer wants to determine how the weight of a car, x, affects gas mileage, y (MPG). The followingdata represent the weights of various cars and their miles per gallon.Make a scatter plot. (Carefullychoose units on both axes; no need tostart at 0, but make them not too small!Do not omit axis labels and the title.)Describe the relationshipbetween Car Weight and MPG.Justify. Give the correlationcoefficient to three decimalplaces. (CV are listed on the lastpage)CarWeight (pounds), xMiles per Gallon, yA B C D E2750 2940 3265 3765 412025.4 25.1 25.4 19.8 20.2If it makes sense, give the equation of the regression line (of MPG on pounds of weight; use at least 3significant, nonzero, digits) and draw this line on the plot (be precise! use a ruler.)Is the gas mileage (miles per gallon) of the car B above average or below average for cars of the sameweight? Justify.What is the best predictor of MPG for a car with weight of 5500 lb. (Be careful!) The graph of the discrete probability below represents the number of live births by a mother 46 to 51years old who had a live birth in 2017.Probability0.30-0.25-0.20-0.150.100.05-0.00-0places.)0.2390.2510.1690.1120.0970.036 0.04135Number of Live Births0.0558Find the means and standard deviation of the probability distribution.

A problem with a phone line that prevents a customer from receiving or making calls is upsetting to both the customer and the telecommunications company. The file “Phone” contains samples of 20 problems reported to two different offices of a telecommunications company and the time toclear these problems (in minutes) from the customers’ lines: Central Office I Time to Clear Problems (minutes) 1.48 1.75 0.78 2.85 0.52 1.60 4.15 3.97 1.48 3.10 1.02 0.53 0.93 1.60 0.80 1.05 6.32 3.93 5.45 0.97 Central Office II Time to Clear Problems (minutes) 7.55 3.75 0.10 1.10 0.60 0.52 3.30 2.10 0.58 4.02 3.75 0.65 1.92 0.60 1.53 4.23 0.08 1.48 1.65 0.72 Assuming that the population variances from both offices are not equal, is there evidence of a difference in the mean waiting time between two offices?

ANOVA. Dr. Milgram is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: df Within-Group:__________ df Between-Groups:___________ Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22) for Group 2: ___________…
1)Should you use the median or mean to describe a data set if the data are not skewed? 2) You may read in the newspaper that a study of a new drug for cancer “increased survival by an average of 8weeks.” It turns out that this is a median, and it is used for complicated statistical reasons. But in a perfectworld, would you prefer to know the increase in mean or median survival? 3) If the median house price is $1.9m, does that necessarily mean that half of the houses on the block areworth less than $1.9m and half worth more?
The following table includes the weekly study time and exam result for each student in a hypothetical class of 20 students. Who knows, perhaps an Analytical Foundations of Math class. Create an Excel spreadsheet that includes the given table and then create a scatter plot, which correctly displays the values from this table. The study times should be the explanatory variable on the x-axis and the exam scores are the response variable on the y-axis. Your spreadsheet should include each of the following items: - Your Name - The given table, including the column titles - A descriptive and easily readable chart title - Descriptive and easy to read titles for both the x and y-axis - A line-of-best fit with the equation of this line also included - Answers to each of the questions below 1. What is the value of the correlation coefficient, r ? 2. What type of correlation best describes the relationship between study time and exam score? a. Strong, Negative Linear association…
Prof. Henderson, always interested in improving her teaching effectiveness, has decided to undertake a careful analysis of her student evaluations from the past several years. The last question on the student evaluation form, Question 17, is "Would you recommend this professor to another student?" A matter of special concern to Prof. Henderson is how she is viewed by students of different majors. Each of Prof. Henderson's students can be placed into a category according to the student's major school. (Students who have majors from more than one school are not included.) So, there are two variables under consideration: student's major school ("School of Social Sciences", "School of Engineering", or "School of Physical Sciences") and answer to Question 17 ("No", "Maybe", or "Yes"). The contingency table below contains a summary of the responses to Question 17 for a random sample of 500 of Prof. Henderson's students. In each cell of the table is written three numbers: the first number is…

There are two basic types of data in social science research: quantitative and qualitative. Which of the following statements is False? A. When done well, neither is easier to do than the other. B. Qualitative and quantitative research are often complementary, but no research should use both qualitative and quantitative data collection and analysis. C. Almost every broad topic can be studied qualitatively or quantitatively. D. In general, the specific research question that one develops within a topic area determines the type of data and method needed to answer it.
