1 Point The Table Shows The Height And Shoe Sizes Of Several Students The following table is a list of women's shoe sizes and their corresponding heights in inches. shoe size: 8.5, 7.0, 7.5, 9.5 height: 66.0, 68.00, 64.5, 65.0, 66.0, 59.0, 62.0, 60, 70.0 . using the 5% significance level, test whether there is a linear correlation between the two variables. step 1: null hypothesis (3pts) step 2: test statistic (8pts). The table shows the heights x (in inches) and shoe sizes y of several students. use a graphing calculator to find an equation of the line of best fit. identify. In this context, we are looking at the relationship between height (in inches) and shoe size for a group of students. the options provided help us explore whether height determines shoe size or shoe size determines height. after reviewing the options and considering the context:. Answer: the predicted height for a student wearing a size 7 shoe is inches. step 1: calculate the slope of the line of best fit using the formula: m = (nΣ(xy) ΣxΣy) (nΣ(x^2) (Σx)^2).
Solved 19 The Table Below Shows The Shoe Sizes Of Some Standard Five In this context, we are looking at the relationship between height (in inches) and shoe size for a group of students. the options provided help us explore whether height determines shoe size or shoe size determines height. after reviewing the options and considering the context:. Answer: the predicted height for a student wearing a size 7 shoe is inches. step 1: calculate the slope of the line of best fit using the formula: m = (nΣ(xy) ΣxΣy) (nΣ(x^2) (Σx)^2). The table shows the heights and shoe sizes of several students. the question asks to find the equation of the line of best fit and the correlation coefficient. explanation:. The shoe size { height scatterplot with the point of averages (s; h) ( the red diamond) and positive and negative quadrants (relative to the point of averages). The table shows the heights x (in inches) and shoe sizes y of several students. an equation of the line of best fit is y = 0.50 x − 23.5 . make a table of the residuals to verify that the model in the example is a good fit. 12 6 the table shows the height and shoe sizes of several \[\begin{array}{|l|l|l|l|l|l|} \hline height (inches) & 65 & 71 & 68 & 69 & 68 \\ \hline shoe size & 9 & 12 & 10 & 10 & 12 \\ \hline \end{array}\] students. use the line of best fit to predict a student's height if they wear a size 7 shoe. 17 inches 59 inches 35 inches 63 inches.
