Manoj and Shira were asked to find an explicit formula for the sequence -9\,,-27\,,-81\,,-243,...β9,β27,β81 ,β243,...Minus, 9, comma, minus, 27, comma, minus, 81, comma, minus, 243, comma, point, point, point. Manoj said the formula is h(n)=-9\cdot3^{\large{n}}h(n)=β9β 3 n h, left parenthesis, n, right parenthesis, equals, minus, 9, dot, 3, start superscript, n, end superscript, and Shira said the formula is h(n)=-3\cdot3^{\large{n}}h(n)=β3β 3 n h, left parenthesis, n, right parenthesis, equals, minus, 3, dot, 3, start superscript, n, end superscript. Which one of them is right?

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
