Q30, ABCD 06-4 Topic 4: Correlation and Regression30. What does correlation do? Select the correct word to complete each sentence.(categorical/quantitative)(a) Correlation measures the strength of the relationship between twovariables.(and/not) direction of the relationship.(b) Correlation measures strength(c) Correlation is appropriate for_(linear/all) relationships.(d) Correlationfrom feet to inches.(increases/decreases/remains the same) when the units are converted1. A detailed study of the veined squid (Loligo forbesii) by Emam et al. showed several interestinglinear relationships in body proportions. Consider the following related data sets.Data 1 Mantel Width: 2.5, 2.1, 2.6, 3, 3.5, 4, 4.4Mantel Length: 0.4, 1.5, 3.7, 3.6, 4.3, 4.5, 4.9Data 2 Mantel Width: 2.5, 2.1, 2.6, 3, 3.5, 4, 4.4Fin Length: 2.3, 2.4, 3.2, 2.9, 3.8, 4.6, 4.3(a) Find the correlation of each data set.(b) Is mantel length or fin length better for predicting mantel width? Explain.Match the correlation with the plot in Figure 7.8.(h) 0 2705(c) 0 9271(d) -0 9564
