Four hours after mechanical ventilation is initiated, a patient’s arterial blood gas (ABG) results include a pH of 7.51, PaO2 of 88 mm Hg, PaCO2 of 26 mm Hg, and HCO3− of 23 mEq/L (23 mmol/L). What change should the nurse anticipate to the ventilator settings to fix the acid-base imbalance?

An economist is studying the job market in area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six neighborhoods gave the following information (units in hundreds of jobs). Data Table Total Jobs, x 17 31 51 29 49 25 Entry-level Jobs, y 2 2 6 5 9 4 Calculate the value of the correlation coefficient (round to three decimal places). Is there a significant correlation between x and y? (yes or no) Calculate the value of the coefficient of determination (round to three decimal places). Find the equation of the least-squares regression line (round each coefficient to three decimal places). y = + x Predict the number of entry-level jobs for a neighborhood with 4000 total jobs (round to the same number of decimal places as y).

Let x represent per capita income in thousands of dollars, and let y represent the number of medical doctors per 10,000 residents. Six small cities gave the following information. Data Table Income, x 8.4 9.2 10.2 8.3 8.3 8.8 # Doctors, y 9.6 18.7 20.8 10.1 11.4 13.1 Calculate the value of the correlation coefficient (round to three decimal places). Is there a significant correlation between x and y? (yes or no) Calculate the value of the coefficient of determination (round to three decimal places). Find the equation of the least-squares regression line (round each coefficient to three decimal places). y = + x Predict the number of medical doctors per 10,000 residents for a small city that has a per capita income of 9.5 thousand dollars (round to the same number of decimal places as y).
