It was discovered that 10 students' marks in two specific topics had a coefficient or rank correlation of 0.5. Later, it was determined that the student's difference in scores across two disciplines had been miscalculated, being recorded as 3, rather than 7. What should the proper value of the rank correlation coefficient be?
Suppose the correlation coefficient between FEV for 100 sets of identical twins is .7, whereas the comparable correlation for 120 sets of fraternal twins is .38. Suppose the correlation coefficient between weight is .78 for the 100 sets of identical twins and .50 for the 120 sets of fraternal twins. *11.12 Test for whether the true correlation coefficients differ between these groups. Report a p-value.
An urn contains 10 white balls and 8 red balls. 2 balls are selected at random. Let X denote the number of red balls drawn and let Y denote the number of white balls drawn. Find the correlation coefficient between X and Y.
How many pairs of observations must be included in a sample so that an observed correlation coefficientof value 0.42 shall have calculated value of t is equal to 2.72?
Suppose that, for a sample of pairs of observations from two variables, the linear correlation coefficient, r , is positive. Does this result necessarily imply that the variables are positively linearly correlated? Explain.
What is the most accurate interpretation of a significant correlation of rs = -.55 between annual CO2 emissions and annual average temperature (ranked from hottest year to coldest year)? Increased CO2 emissions are associated with lower annual average temperature Increased CO2 emissions are associated with higher annual average temperature Increased CO2 emissions lead to higher annual average temperature Increased CO2 emissions lead to lower annual average temperature If we conducted a study with a small group of randomly selected first- year psychology students and found a Pearson’s r of -.39 between distance from home to university (measured in km) and class attendance, what could we say about the relationship in the population? University students who live far from their homes are less likely to attend class There is no relationship between distance between home and university with class attendance University students who live far from their homes are more likely to attend…
Suppose that, for a sample of pairs of observations from two variables, the linear correlation coefficient, r , is negative. Does this result necessarily imply that the variables are negatively linearly correlated? Explain.
The maximum weights (in kilograms) for which one repetition of a half squat can be performed and the jump heights (in centimeters) for 12 international soccer players are shown in the attached data table with a sample correlation coefficient r of 0.771. Remove the data entry for the international soccer player with a maximum weight of 180 kilograms and a jump height of 64 centimeters. Describe how this affects the correlation coefficient r.
The marketing head of a leading chocolate manufacturer must decide amongfour different wrapper styles for the chocolate. To provide a database for the decision, he hasthe chocolate placed in the different wrappers and distributes them to five supermarkets. At the end of 2 weeks, he finds that the following amounts of chocolate were sold: Wrapper A Wrapper B Wrapper C Wrapper D 90 98 130 82 compute the Pearson correlation coefficient (Chi Square Test)
For a data set of brain volumes (cm3) and IQ scores of five males, the linear correlation coefficient is found and the P-value is 0.619. Write a statement that interprets the P-value and includes a conclusion about linear correlation. The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is nothing%, which is ▼ high, low, so there ▼ is is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males. (Type an integer or a decimal. Do not round.)
If the coefficient of correlation between two variables is -0.6, What is the coefficient of non-determination?
The correlation coefficient between daily ration of green grass and rate of growing calves on the basis of observations taken on 10, 14, 16, 20, 25 and 28 cows at six farms were found to be 0.318, 0.106, 0.253, 0.340, 0.116 and 0.112. Can these be considered homogeneous ? If so, estimate the common correlation coefficient.
