It is known that the slope coefficient for regression line Y on X is 0.942 The standard deviation of X and Y are 5 and 9 respectively. Find the value of the correlation coefficient for using given information.
So I generated this table with stat program, which is from a regression of temperature (in °C) on atmospheric concentrationof carbon dioxide (CO2), in ppm. Can you please construct a 95% confidence interval for the slope of the regression equation? Also, what are the chances of seeing a linear relationship at least as strong as observed from these data, when in fact there was none in the population? What would be the conclusion from this regression?
A sample of 100 bears was treated like it was the whole population of Jellystone Park bears, and the mean weight was found to be 800 pounds with standard deviation 12 pounds, the mean blood pressure was 150 with standard deviation 6, and the sample correlation coefficient of weight with blood pressure was found to be .4. Based on this information, what is the regression slope for the SLR equation for predicting blood pressure using observed weight for Jellystone bears?
An international organization is investigating the relationship between the life expectancies of men and women in nonindustrialized countries. A random sample of such countries was selected, and life expectancies, in years, were determined for both men and women. A check of the conditions necessary for inference on the slope of a regression line shows that they are met. A 98 percent confidence interval for the slope of the regression line relating life expectancy for men, xx, and women, yy, is given by (1.01,1.34)(1.01,1.34). Based on the interval, which of the following claims is supported? A. Since the interval does not contain 0, it can be concluded that there is no linear relationship between the life expectancies of men and women in nonindustrialized countries. B. Since the interval does not contain 1, it can be concluded that there is no linear relationship between the life expectancies of men and women in nonindustrialized countries. C. Since the values in the interval are…
The estimated regression line is defined as the straight line that: touches the most points in the scatter diagram. minimizes the sum of the absolute deviations between the line and the corresponding observations. minimizes the sum of the squared vertical distances between each observation and the line. none of the above
Dr. S. compared her experimental group to a control group using a t test and concluded that her t was significant at the 1% level. If Dr. S. replicates her study using a similar sample of participants, she is most likely: to find that the experimental group is different from the control group; to find that the experimental group is similar to the control group; to find that the distribution of scores in the experimental group resembles a normal curve; however, the distribution of scores in the control group does not resemble a normal curve; d. The experimental group scores were correlated with the control group scores
The following table shows the starting salary and profile of a sample of 10 employees in a certain call center agency. Run a multiple regression analysis with starting salary as the dependent variable (pesos) and GPA, years of experience and civil service ratings as the independent variables. Use .05 level of significance.In the ANOVA F test output, what is the computed F and the conclusion of the test regarding the overall significance of the model? Computed F stat = 27.51. Reject Ho. Therefore, the resulting regression model overall predicts the starting salary significantly well. Computed F stat = 27.51. Ho is not rejected. Therefore, the resulting regression model is not significant. Computed F stat = 123.71. Ho is rejected. Therefore, the resulting regression model overall predicts the starting salary significantly well. Computed F stat = 212.56. Reject Ho. Therefore, the resulting regression model overall predicts…
The new manager of an Information Technology company collected data for a sampleof 20 computer programmers in the organization to perform a multiple regressionanalysis on the structure of their salaries. The aim of this manager in this exercise is todetermine if the Salary (y) of a hired computer programmer was related to the years ofExperience (??) in the organization and also the Score (??) of the programmers duringtheir first interview aptitude test scores. The years of experience, score on the aptitudetest and the corresponding annual salary (in thousands of Ghana cedis) for a sample ofthe 20 programmers is shown in the Regression statistics table below;Experience (??)(in years)Score (??)(out of 100%)Salary (y)(GH¢ 000)4 78 247 100 431 86 23.75 82 34.38 86 35.810 84 380 75 22.21 80 23.14 | P a g e6 83 306 91 339 88 382 73 26.610 75 36.25 81 31.66 74 298 87 344 79 30.16 94 33.93 70 28.23 89 30Managerial Report 2:Use Multiple Regression Analysis to help management develop a Salary…
