Step 1
We are given the following data: - Sample mean (x̄) = 13.399 g/dL - Sample standard deviation (s) = 1.416 g/dL - Sample size (n) = 100 Show more…

Hemoglobin levels (g/dL) in 100 randomly selected adult females were measured. These were the results: x̄ = 13.399, s = 1.416, n = 100 Using a 90% confidence level, find the margin of error, E. a. 1.99 b. 0.235 c. 0.372

The hemoglobin count (HC) in grams per 100 milliliters of whole blood is approximately normally distributed with a population mean of 14 for healthy adult women. Suppose a particular female patient has had 18 laboratory blood tests during the past year. The sample readings showed an average HC of 14.16 with a standard deviation of 2.55. Does it appear that the population average HC for this patient is not 14? (a) State the null and alternative hypotheses: (Type "mu" for the symbol μ , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1) H0 : HA : (b) Find the test statistic, t =

The hemoglobin levels for healthy adult females are approximately normally distributed with a mean of μ = 17 and standard deviation σ = 0.9. X ~ N(17, 0.9^2) a. Find the probability that a randomly chosen healthy female adult has a hemoglobin level i. Less than 15 [3] ii. Between 16 and 18 [4] iii. More than 17.5 [3] b. Find the probability that the mean hemoglobin level of a group of five adult females will be above 17.5 [4] c. Find the probability that the mean hemoglobin of a group of 20 female adults will be between 17.5 and 17.75 [4] d. Find the hemoglobin level X for which 90% of the adult females have hemoglobin level less than X
