Asap male and female high school students reported how many hours they worked each week in summer jobs. the data is represented in the following box plots: two box plots shown. the top one is labeled males. minimum at 0, q1 at 3, median at 10, q3 at 15, maximum at 35. the bottom box plot is labeled females. minimum at 0, q1 at 2, median at 6, q3 at 9, maximum at 14 identify any values of data that might affect the statistical measures of spread and center. the zero hour mark on both plots prevents the graphs from being balanced. the median is near the center of the iqr for both males and females. there is not enough evidence to see any effects on spread or center. the males have a suspected significant high outlier.

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
