Question
The image is a screenshot displaying statistical analysis from a Minitab output on the relationship between the body weight of a child (in kilograms) and the metabolic rate of the child (in 100 kcal/24 hr). ### Statistical Output **Predictors:** 1. **Constant:** - Coefficient (Coef): 0.8408 - Standard Error of Coefficient (SE Coef): 0.4148 - t-value (T): 2.06 - p-value (P): 0.054 2. **Weight:** - Coefficient (Coef): 0.3906 - Standard Error of Coefficient (SE Coef): 0.0289 - t-value (T): 13.52 - p-value (P): 0.000 **Model Summary:** - S = 0.137500 - R-Sq = 95.0% ### Questions (a) **Write out the least-squares equation.** - Input field for equation: \(\hat{y} = 0.8408 + 0.3906x + 95.0\) (b) **For each 1 kilogram increase in weight, how much does the metabolic rate of a child increase?** - Input field for increase in metabolic rate (in 5 decimal places). (c) **What is the value of the correlation coefficient r?** - Input field for correlation coefficient (use 3 decimal places). ### Additional Information Below the statistical data, there are options to submit the answer, save assignment progress, and buttons such as "Need Help?" that link to additional resources.
