Question 5 (1 point) In a study in 1998, the following equation for predicting baby birth weight in grams (Y) given mothers age in years (X): 1? = 4163.45 + 245.15-X. If the RMS=589.3 grams, about 95% of the babies born to a 22-year-old mothers will weigh between _____ grams and ______grams. Hint: make sure to carry calculations to at least 4 places past the decimal. Q A) (6508.95, 7044.75) 0 B) (4687.55, 5866.15) 0 C) (3051.25, 5408.49) O D) (1726.5, 5262.3) 0 E) (2315.8, 4673.0) Previous Page Next Page Page 5 0f 11 Question 6 (1 point) Suppose you studied the effects of temperature (degrees Celsius) on respiratory rates (measured in ,uLOngDW_1h_1) among female copepods (small crustaceans) in a Moroccan marine coast environment. You calculated a correlation coefficient of 0.89. If the temperature is at the 65th percentile, what can you say about the predicted percentile for respiratory rate? [Hint: Recall the regression effect] 0 The predicted percentile for respiratory rate is equal to the 50th percentile. O The predicted percentile for respiratory rate is equal to the 89th percentile. O The predicted percentile for respiratory rate is higher than 89th percentile. O The predicted percentile for respiratory rate is higher than the 65th percentile. O The predicted percentile for respiratory rate is lower than the 65"h percentile. Previous Page Next Page Page 6 Of 11
