Twenty different statistics students are randomly selected. For each of them, their body temperature (C) is measured and their head circumference (cm) is measured. a. For this sample of paired data, what does r represent, and what does p represent? b. Without doing any research or calculations, estimate the value ofr. c. Does r change if body temperatures are converted to Fahrenheit degrees? a. Choose the correct answer be elow. O A. ris a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and pis a parameter that represents the value of the linear corelation coefficient that would be computed by using all of the paired data in the population of all statistics students. OB. ris a statistic that represents the proportion of the variation in head circumference that can be explained by variation in body temperature, and p is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students. OC. ris a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and pis a parameter that represents the proportion of the variation in head circumference that can be explained by variation in body temperature. OD. ris a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students, and pis a statistic that represents the value of the linear correlation coefficient computed from the paired sample data b. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal ro one decimal place as needed) A. The value of ris estimated to be. because it is likely that body temperature and head circumference are strongly negatively correlated. O B. The value of r is estimated to be. because it is likely that body temperature and head circumference are strongly positively correlated OC. The value of ris estimated to be. because it is likely that there is no corelation between body temperature and head circumference. c. Choose the correct answer below. O A. The value of r changes, because r is affected by converting all values of a variable to a different scale OB. The value of r does not change, because r is not affected by the choice of x or y OC. The value of r does not change. because r is not affected by relationships that are not linear. OD. The value of r does not change, because r is not affected by converting all values of a variable to a different scale.

For the following questions, THERE IS NO NEED FOR EXPLANATION. PLEASE PROVIDE JUST THE ANSWER THANK YOU. Please DO NOT waste time on writing things to explain. Please answer in 30 mintues or else I will write a bad review. If you follow my rules and answer in less than 30 mintues then I will write a very long and wonderful review about you.

Important: This question continues from the previous two questions and onto the following two questions. A Rasmussen Reports national survey of 1000 random adult Americans found that 6% felt that Saint Patrick's Day was one of our nation's most important holidays. From the previous question, input the calculated number of successes and number of failures. Show your work on your scratch paper. The number of successes is The number of failures is .Write your answer as a whole number. . Write your answer as a whole number.

Researchers have been studying the reliability of a new medical test. On their last study, they found that the test accurately identified those with the disease 92% of the time, and it accurately identified those without the disease only 74% of the time. There were 1,000 total people in this study, and 200 of them had the disease. Complete the table below using this information. Then, use your completed table to help you answer the questions.

In a traditional class with in-class tests, a question that is often asked after a class exam is, "What was the class average?" If that question is asked and the professor says that the class average was 80, what information do the students gain by knowing that? I want you to focus on both what the individual students knows about their own grade as well as what the students know about the class's grades on that exam.

Many graduate school programs in the United States require applicants to take the Graduate Record Exam, also called the GRE. One part of the exam, the GRE-Quantitative test, assesses students' level of quantitative reasoning and thinking - exactly the skills we are building in our class this semester. The highest score possible on the GRE-Quantitative test is a score of 800. Many graduate schools think that a score of 700 or higher on the GRE-Quantitative test shows that the applicant has strong quantitative skills. The table shows the number of people who took the GRE between 2003 and 2006 who had GRE-Quantitative test Scores of 700 or higher. All of the people represented in the table planned to major in one of the two listed areas of the social sciences. a. Complete the table.

Hello. Can I get help on how to work this problem? Thank You!

Help please with P-value. How to compute in excel or statcrunch would be helpful.

The scores of a test for an engineering class of 30 students are shown here. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) Scores: 81, 54, 55, 56, 96, 86, 98, 61, 90, 52, 92, 76, 66, 84, 79, 70, 71, 88, 62, 74, 53, 65, 55, 78, 79, 58, 60, 72, 51,80 (a) Determine the frequency (f), midpoint (x), and xf for each range and fill in the table below. (First, organize the scores into the following ranges: 50-59, 60-69, 70-79, 80-89, and 90-99.) (b) Using the following equation, determine the mean value (x) and fill in the table below. Σ(XA) n X = (c) Calculate (x − x) for each range and fill in the table below. (d) Calculate (x - x)²f for each range and fill in the table below. Range Frequency f Midpoint x 50-59 60-69 70-79 80-89 90-99 S = Enter a number. S = (e) Using the following equation, compute the standard deviation of the class scores.
