Click right here to view ALL problems on Probability-and-statisticsQuestion 177113: which of the complying with statements concerning the coefficient that correlation is true? A) It ranges from -1.0 come +1.0 inclusive B) It steps the stamin of the relationship between two variables C) A worth of 0.00 suggests two variables are not connected D) all of the above E) nobody of the aboveWhich value of r suggests the strongest correlation? A) -0.30 B) -0.50 C) +0.48 (would C it is in correct?) D) 0.00 E) none of the aboveWhat does a coefficient the correlation the 0.70 mean? A) virtually no correlation because 0.70 is close to 1.0 B) 70% of the sports in one variable is defined by the various other C) Coefficient of decision is 0.49 D) Coefficient the nondetermination is 0.30 E) nobody of the aboveWhat is the selection of values for a coefficient of correlation? A) 0 to +1.0 B) -3 to +3 inclusive C) -1.0 come +1.0 inclusive D) Unlimited selection E) no one of the aboveIf the correlation coefficient in between two variables equals zero, what can be claimed of the variables X and Y? A) Not associated B) dependency on each various other C) Highly correlated D) all of the over are exactly E) nobody of the over is correctWhat deserve to we to speak if the coefficient of determination is 0.94? A) stamin of connection is 0.94 B) Direction of relationship is confident C) 94% of complete variation in one change is explained by variation in the other variable D) all of the over are exactly E) none of the above is correctWhat go the coefficient of determination equal if r = 0.89? A) 0.94 B) 0.89 C) 0.79 D) 0.06 E) nobody of the aboveWhat go it typical if r = -1.00? A) dependent variable can be perfectly predicted by the independent variable. B) every one of the sports in the dependence variable can be accounted for by the elevation variable. C) High worths of one variable are associated with low values of the other variable. D) Coefficient of determination equals one. E) every one of the above are correctA hypothesis test is conducted at the .05 level of significance to check whether or no the population correlation is zero. If the sample consists of 27 observations and also the correlation coefficient is 0.60, then what is the computed worth of the check statistic? A) 4.69 C) 4.75 B) 3.75 D) 18.75 E) no one of the aboveWhat is the range of values for the coefficient that determination? A) -1 to +1 inclusive B) -3 come +3 inclusive C) -1 come 0 inclusive D) 0 come +1 inclusive E) nobody of the aboveIn the regression equation, what go the letter "a" represent? A) Y intercept B) slope of the line C) any value that the elevation variable the is selected D) nobody of the above Answer by stanbon(75887)
