Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Textbook Question

Chapter 17, Problem 53E

Exercises 53 through 56 refer to the distribution of weights for infants by age and gender. In all cases you can assume that the weight distribution is approximately normal. The data for these exercises are taken from the 2000 clinical growth charts by the Centers of Disease Control and Prevention (CDC) (www.cdc.gov/growthcharts/clinical_charts.htm).

The distribution of weights for six-month-old baby boys has mean μ = 8.16 kg and standard deviation σ = 0.95 kg .

a. Suppose that a six-month-old boy weighs 7.21 kg.

Approximately what weight percentile is he in?

b. Suppose that a six-month-old boy weighs 10 kg.

Approximately what weight percentile is he in?

c. Suppose that a six-month-old boy is in the 75 t h percentile in weight. Estimate his weight to the nearest tenth of a kilogram.
