Question
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 thirteen blood tests for uric acid. The

(b)
What conditions are necessary for your calculations? (Select all that apply.)
n is large? is unknownuniform distribution of uric acidnormal distribution of uric acid? is known
(c)
Interpret your results in the context of this problem.
We are 95% confident that the true uric acid level for this patient falls within this interval.
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.
We are 5% confident that the true uric acid level for this patient falls within this interval.
(d)
Find the sample size necessary for a 95% confidence level with maximal margin of error E = 1.18 for the mean concentration of uric acid in this patient's blood. (Round your answer up to the nearest whole number.)

Scores are normally distributed. A. Draw the normal curve and label it with raw scores for mean, plus and minus one standard deviation, plus and minus two standard deviations. (You will have 5 marks along the x axis in all.) B. What is the probability of a score lower than 145? C. What is the probability of a score higher than 162.5? D.

There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if their glucose level is above 140 mg/dl one hour after consuming a sugary drink. Sheila's measured glucose level one hour after the sugary drink varies according to the Normal distribution, with p = 125 mg/dl ando = 10 mg/dl. Fill in the following blanks with the correct options: (a) If a single glucose measurement is made, the probability that Sheila is diagnosed as having gestational diabetes is (0.0668, 0.1587, 0.2525, or 0.3173?). (b) Assuming that the population mean is 125 mg/dl, imagine that we repeat taking all possible samples of size 4 from the population, then only about 1.3 out of (10, 100, or 1,000?) sample means will have values as large as (125 or 140?) cm or even larger.arrow_forward

- Sunscreens are products that protect the skin from skin cancer by preventing the sun's ultraviolet (UV) radiation from penetrating the skin. According to dermatologists, the recommended amount of sunscreen needed to cover the exposed areas of the body is at least an ounce. In a study conducted specifically for a group of women aged 21 to 30 years, it was found the amount of sunscreen (X) applied by the group follows the normal distribution with mean of 0.6 ounce and standard deviation of 0.25 ounce. About ___% of the women aged 21 to 30 years is applying 0.1 to 1.1 ounce ofarrow_forwardOverproduction 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 eight blood tests for uric acid.

This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123123 mg/dL and a standard deviation of 4141 mg/dL. If an individual's LDL is at least 11 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 11 or more standard deviations above the mean? Use the 6868–9595–99.799.7 rule.
