Does it make sense to set up the requested confidence interval? if so, can the normal curve (central limit theorem) be used it be set it uups? the average math sat score of all incoming freshman at a large university is 490. a simple random sample of 200 of these incoming freshmen has an average math sat score of 495 with a standard deviation of 60, set up an approximate 95% confidence interval for the average math sat score of all incoming freshmen at the university. select only one of the boxes below.
a. it makes sense, but the normal curve cannot be used to make the requested confidence interval.
b. it is appropriate and makes sense to compute a confidence interval using the normal curve.
c. making the requested confidence interval does not make sense.

if it is appropriate to compute a confidence interval for this problem using the normal curve, then enter the confidence interval below. otherwise, enter [0,0] for the confidence interval.

Overproduction of uric acid in the body can be an indication of cell breakdown. this may be an advance indication of illness such as gout, leukemia, or lymphoma.† over a period of months, an adult male patient has taken nine blood tests for uric acid. the mean concentration was x = 5.35 mg/dl. the distribution of uric acid in healthy adult males can be assumed to be normal, with σ = 1.87 mg/dl. (a) find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. what is the margin of error? (round your answers to two decimal places.) lower limit upper limit margin of error (b) what conditions are necessary for your calculations? (select all that apply.) σ is unknown n is large σ is known normal distribution of uric acid uniform distribution of uric acid (c) interpret your results in the context of this problem. there is not enough information to make an interpretation. the probability that this interval contains the true average uric acid level for this patient is 0.05. the probability that this interval contains the true average uric acid level for this patient is 0.95. there is a 95% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. there is a 5% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. (d) 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. (round your answer up to the nearest whole number.) blood tests
