You are a respiratory therapist assigned to the ICU of a local hospital and have been called to assess a patient who may require mechanical ventilation. Physical examina-tion reveals a respiratory rate of 25, blood pressure 145/90, pulse 115, and breath sounds are bilaterally decreased, especially in the bases. The arterial blood gas reveals: pH 7.44 PaCO2 36 mm Hg PaO2 42 mm Hg SaO2 70% HCO3 − 22 mEq/L Device: a nonrebreather mask at 10 L/min The patient’s maximal inspiratory pressure is –75 cm H2O, VC is 70 mL/kg, and VT is 7 mL/kg.  

df.isnull().sum() returns the number of missing values per column.

[R] You have a tibble called students with columns name, major, and gpa. Using dplyr, write a pipeline that: (a) filters to students with a GPA of 3.5 or higher, (b) groups by major, and (c) calculates the average GPA per major, sorted in descending order.

Governments must adopt a(n) [BLANK-1] approach to climate migration in order to balance immediate needs with long-term resilience. 

Data documentation is optional if the analyst plans to share the cleaned dataset with colleagues.

A dataset of employee salaries has 15% of its age values missing. Describe TWO different strategies for handling these missing values. For each strategy, explain when it is appropriate and what risk it introduces.

A professor collects exam scores from 30 students. The mean score is 72 and the median is 65. What does this difference tell you about the distribution? What additional statistic(s) would you calculate to further understand the shape, and why?

In R’s tidyverse, which dplyr function keeps only rows that meet a condition?

Based upon the following patient information, calculate the patient’s static lung compliance: exhaled tidal volume (VT) is 675 mL, peak inspiratory pressure (PIP) is 28 cm H2O, plateau pressure (Pplat) is 8 cm H2O, and PEEP is set at 5 cm H2O.
