A fisheries biologist has been studying horseshoe crabs using categorical variables, but she has decided that reporting the data as continuous variables would be more useful. She has sampled 100 horseshoe crabs and recorded their weight (in kilograms) and width (in centimeters). The proposed regression equation is weight_i = beta_0 + beta_1 Times width_i + epsilon_i, where the deviations epsilon_i are assumed to be independent and Normally distributed with mean 0 and standard deviation sigma. This model was fit to the data using the method of least squares. The following results were obtained from statistical software. A 95% confidence interval for the slope beta_1 in the simple linear regression model is (approximately) Select one:. a. 2.3013 plusminus 1.9419. b. 2.3013 plusminus 0.1863. c. 0.7963 plusminus 1.9419. d. 0.7963 plusminus 0.1863.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
