Hello Tutor,

Could you please explain how to properly solve this question using R and the corresponding codes that goes with it.

1.)Blood calcium levels are measured in mg/dL. In patients over 30, = 9.55 mg/dL, and = 2.27 mg/dL. Again, use R.

a) Give the blood calcium values for the middle 50% of patients.

b) Give the blood calcium values for the middle 90% of patients.

c) Give the 95th percentile.
