0 Question 20 v Suppose that a: 2 hours of TV time during the week and y 2 score on an exam. For the regression equation 3; = 48 7:1: Interpret: a The y-intercept '33::3' A student who does not watch TV at all would be expected to score 48 points '33:? A student who does not watch TV at all would be expected to score 7 points '33:? Every extra hour of TV time should result in a 48 point decrease in score '33:? Every extra hour of TV time should result in a 7 point decrease in score b. The slope '33::3' A student who does not watch TV at aLL would be expected to score 48 points '3' Every extra hour of TV time should result in a 7 point decrease in score '3' A student who does not watch TV at all would be expected to score 7 points '3' Every extra hour of TV time should result in a 48 point decrease in score . Question 21 V After collecting data about how many hours per week full time students spend studying (3:) and what their GPA is {'9}, you come up with this regression equation: 3; = 1.29 + 0.06:3 Interpret: a. The slope '3' Every extra hour of study should result in a 0.06 point increase in GPA '33:? Astudent who does not study at all would be expected to have a GPA of 0.06 points '33:? Astudent who does not study at all would be expected to have a GPA of 1.29 points '33:? Every extra hour of study should result in a 1.29 point increase in GPA b. The y-intercept '33:? Astudent who does not study at all would be expected to have a GPA of 1.29 points '3' Every extra hour of study should result in a 1.29 point increase in GPA '3' Astudent who does not study at all would be expected to have a GPA of 0.06 points '3' Every extra hour of study should result in a 0.06 point increase in GPA . Question 22 v Suppose that :1: 2 age of an infant {in months} and y 2 hours slept in a day. For the regression equation y = 13.9 0.17m Interpret: a. The slope '3' A newborn baby would be expected to sleep [1.17 hours per day '33:? A newborn baby would be expected to sleep 13.9 hours per day '11:? Every extra month of age should result in a 13.9 hour decrease in hours slept per day '11:? Every extra month of age should result in a 9.1? hour decrease in hours slept per day b. The y-intercept '3' Every extra month of age should result in a 13.9 hour decrease in hours slept per day '3' A newborn baby would be expected to sleep [1.17 hours per day '3' A newborn baby would be expected to sleep 13.9 hours per day '3' Every extra month of age should result in a 9.1? hour decrease in hours slept per day
