Can I have help with this?

0 Last month, an adult male patient took 3 blood test samples for uric acid. The mean uric acid cgncentration from those 8 blood test samples was f=5.35 mg/dL. It can be assumed that the random variable X, that represents the 'uric acid concentration in healthy adult males', is approximately ndrmally distributed with 0:1.85 mg/dL. a. [2 points] Are the requirements needed to solve the part b of question 6 satisfied? Explain. b. [5 Points] Find a 95% confidence interval for the population mean u, the concentration of uric acid in this patient's blood. Find E, the margin of error. Interpret your result. c. [ 3 Points] Find the sample size necessary for a 95% confidence level with maximal margin of error E=1.10 for the mean concentration of uric acid in this patient's blood
