Question 26 (4 points) Which of the following statements is/are true about confidence intervals (Cls)? 1. A 99% Cls provides a narrower interval compared to 95% Cls. 2. Cls are used to estimate the population based on sample data. 0 A) Statement 1 and 2 O B) Statement 2 only 0 C) None of the two statements 0 D) Statement 1 only Previous Page Next Page Page 9 Of 9 Question 24 (4 points) The mean arterial pressure (or MAP, average arterial pressure in one cardiac cycle) is a measure for perfusion status. You are interested to know if it is possible to predict an adult's MAP (Y) based on the body surface area (X). Suppose you randomly selected 50 adults, and measured their mean arterial blood pressure (in mmHg) & body surface area (in m2). The results are reflected below: x =1.6 Sx =0.5 y =80.1 sy = 16.9 r = 0.8 [Source: Nall, R. (2018, April 10). Mean arterial pressure: Normal, low, high readings plus treatment. Retrieved from https://www.healthline.com/health/mean-arterial-pressure] O What is the predicted value for MAP if a person has 1.66 m as his body surface area? ( A) 70.50 mmHg ( B) 90.10 mmHg O C) -56.23 mmHg D) 81.72 mmHg O O E) 88.19 mmHgQuestion 25 (4 points) The Philippine eagle, the national bird of the Philippines, is one of the endangered species in the planet. This is attributed to the fact that they breed once every 2 years, and that average time to hatching of their offspring is 63 days. [Source: Sison, F. (n.d.). Pithecophaga Jefferyi (great Philippine eagle). Retrieved from https://animaldiversity.org/accounts/Pithecophagajefferyi/J Suppose the time of hatching has a standard deviation of 14 days.
