Question A study of the nutrition pf dialysis patient measured the level of phosphorus in the blood of sever patients on SIX occasions. Here are the data for ONE patient. 5.5, 5.2, 4.4, 4.9, 5.7, 6.2. The measurements are separated in time and can be considered on SRS of the patient’s blood phosphorus level. Assume that this level varies Normally with o=0.9mg/dl. Round you answers to three decimal places.a. Give a 95% confidence interval for the mean blood phosphorus level. _________________________, __________________________How is this calculated?
