A researcher wants to estimate the population mean cost of concert tickets in a major city. She collects a random sample of 26 ticket prices and finds the sample mean is $185 with a sample standard deviation of $24.50. The Minitab output for the 90% confidence interval for the true mean cost of concert tickets is provided: How will the assumption of normality be determined?

A 68-year-old male with a history of hypertension and chronic kidney disease is admitted to the ICU with sepsis secondary to pneumonia. He is hemodynamically stable on low-dose norepinephrine and has no active bleeding. His hemoglobin level is currently 7.1 g/dL. According to the guidelines, what is the most appropriate transfusion strategy for this patient?

A 72-year-old female is admitted to the ICU with acute respiratory failure requiring mechanical ventilation. On admission, her hemoglobin was 10.1 g/dL and has dropped to 7.9 g/dL by day 4 of hospitalization. She is hemodynamically stable, afebrile, and has no signs of bleeding. Her reticulocyte count is low, and iron studies show normal ferritin and transferrin saturation. What is the most appropriate next step in management?
