Question 8 1 pts Mika examined whether ocean water depth was related to available oxygen levels. She took 8 random samples and gathered the following data: 20 60 40 depth The regression line was calculated to be y = 65.35 +-0.6x. The residual sum of squares was 2717.4. Use the table below to calculate the Goodness-of-fit F ratio value for this regression model. You -F can assume the mean oxygen level is 46.5. Give your answer to two decimal places. Water Depth Oxygen Levels y. lygy Mean Oxygen level 5 81 46 5 34.5 1190.25 15 44 46 5 -2.5 6.25 22 65 46 5 18.5 342.25 43 62 46.5 15.5 240.25 47 50 46 5 61 16 46.5 20 19 46 5 -27,5 756.25 40 35 46.5 - 11.5 132.25

Question 14 1 pts Import the states.csv, from your data folder, into Rstudio. Then run a linear regression to investigate if waste is predicted by pop (population). What is the correct Standard Error of the Estimate Oest for this data? 0.2762 What is the correct F ratio for this data? 48

Question 4 1 pts Select the magnitudes of the values below that correspond to a model with a good fit. R-squared Large Small Standard Error of the Estimate > F-ratio Large p-value Small
