You are given a csv file (outcomes.csv) that represents the outcomes of patients admitted to ICU. There are 4 columns

a. RecordID: record id of a patient.

b. Length of stay (days): number of days between the patient's admission to the ICU and the end of hospitalization. Missing values are indicated as NA.

c. Survival (days): If the patient's death was recorded (in or out of hospital), then Survival is the number of days between ICU admission and death; otherwise, Survival is assigned the value -1.

d. In-hospital death (0: survived during hospital stay, or 1: died-in-hospital)

Write R code to find the following:

A. Number of patients who survived during their stay in hospital.

B. Number of patients who died during their stay in hospital.

C. Average of number of survival days among the patients who died-in-hospital.

D. Among the patients who survived during their stay in hospital, how many of them stayed in the hospital for least 5 days.

E. Among the patients who survived during their stay in hospital, how many of them stayed in the hospital less than 7 days
