Question 1 2 pts (02.01) Ophthalmology students compared two types of detached retina surgery to determine if patients were able to regain vision. They studied laser surgery and freezing treatment. Identify the response and explanatory variables. 0 The response variable is the type of retina surgery. and the explanatory variable is the amount of vision the patients obtained after surgery. 0 The response variable is the amount ofyision the patients obtained after surgery. and the explanatory variable is the type of retina surgery. 0 The response variable is laser surgery. and the explanatory variable is freezing treatment. 0 The response variable is freezing treatment. and the explanatory variable is the amount of vision the patients obtained after surgery. 0 The response variable is freezing treatment. and the explanatory variable is laser surgery. \fQuestion 3 [02.01) Venus's atmosphere is divided into layers including the troposphere, thermosphere, etc; The troposphere is the layerthat is closest to Venus's surface. The distance from Venus and the troposphere's sulfuric acid content have a positive associah'on. Interpret the meaning ofthe positive association with respect to the sulfuric acid content 0 As you move closer to Venus. the sulfuric acid content increases. As you move away from Venus. the sulfuric acid content decreases Q As you move away from Venus. the sulfuric acid content remains the same. 0 As you move away from Venus. the sulfuric acid content increases. 0 As you move closer to Venus. the sulfuric acid content remains the same. 2 pts Question 4 2 pts [02.01) The height of daisies with respect to number of days growing was recorded for 35 days. The correlation coefcient was calculated to be r = 0.9363. Interpret the meaning of the correlation coefcient in terms of the scenario. 0 There is a strong. positive correlation between the height of daisies and the number of days growing. 0 There is a strong. negative correlation between the height of daisies and the number of days growing. 0 There is a weak. positive correlation between the height of the daisies and the number of davs growing. 0 There is no correlation between the number of davs growing and the height of the daisies. Q There is a weak. negative correlation between the number of davs growing and the height of the daisies. Question 5 2 pts (02.01} The correlation between two scoreS X and Y equals 0.92. If both scoreS were converted to z-scores, then the correlation between the z-5core5 for X and 2-5core5 for '1' would be 0 0.92 O 0.92 O 0.03 O 0.08 O 0.0
