Growth charts We used an online growth chart to find percentiles for the height and weight of a 16-year-old girl who is 66 inches tall and weighs 118 pounds. According to the chart, this girl is at the 48th percentile for weight and the 78th percentile for height. Explain what these values mean in plain English.

Short Answer

Expert verified

She is taller than 78% of females, yet she only weighs 48% more than girls, thus she will most likely be much leaner.

Step by step solution

01

Step 1. Given

A 16-year-old girl stands at 66 inches tall. A 16-year-old girl's weight is 118 pounds. The girl is in the 48th percentile for weight and the 78th percentile for height, according to the chart.

02

Step 2. Concept

A score in the 95th percentile is a figure on a scale of 100 that represents the percent of a distribution that is equal to or below it.

03

Step 3. Explanation

The height and weight are 66inches and 118pounds, respectively.

The girl's weight is in the 48thpercentile, and her height is in the 78thpercentile.

The girl's height is66inches, and 78%of girls are shorter than 66inches because she is in the 78thpercentile. Her height is above average at the 78thpercentile, indicating that she is a growing girl. The girl's weight is 118pounds, and she is in the 48thpercentile, which means she is lighter than 48%of girls her age. Her weight is in the 48thpercentile, indicating that she is slightly underweight. She will most likely be a woman because she is taller than 78%of females but only weighs 48%more.

Cool pool? Coach Ferguson uses a thermometer to measure the temperature (in degrees Celsius) at 20different locations in the school swimming pool.

An analysis of the data yields a mean of25°Cand a standard deviation of 2°C. Find the mean and standard deviation of the temperature readings in degrees Fahrenheit (recall that °F=(9/5)°C+32)

The distribution of heights of adult American men is approximately Normal with mean 69inches and standard deviation of 2.5inches. Draw a Normal curve on which this mean and standard deviation are correctly located. (Hint: Draw the curve first, locate the points where the curvature changes, then mark the horizontal axis.)

R2.10 Grading managers Many companies "grade on a bell curve" to compare the performance of their managers and professional workers. This forces the use of some low-performance ratings, so that not all workers are listed as "above average." Ford Motor Company's "performance management process" for a time assigned 10%A grades, 80%B grades, and 10%C grades to the company's 18,000managers. Suppose that Ford's performance scores really are Normally distributed. This year, managers with scores less than 25received C's, and those with scores above 475received A's. What are the mean and standard deviation of the scores? Show your work.

Comparing batting averages Three landmarks of baseball achievement are Ty Cobb’s batting average of 420in 1911, Ted Williams’s 406in 1941, and George Brett’s 390in 1980. These batting averages cannot be compared directly because the distribution of major league batting averages has changed over the years. The distributions are quite symmetric, except for outliers such as Cobb, Williams, and Brett. While the mean batting average has been held roughly constant

by rule changes and the balance between hitting and pitching, the standard deviation has dropped over time. Here are the facts: Compute the standardized batting averages for Cobb, Williams, and Brett to compare how far each stood above his peers.

T2.3. Rainwater was collected in water collectors at 30different sites near an industrial complex, and the amount of acidity (pH level) was measured. The mean and standard deviation of the values are 4.60and 1.10, respectively. When the pH meter was recalibrated back at the laboratory, it was found to be in error. The error can be corrected by adding 0.1pHunits to all of the values and then multiplying the result by 1.2. The mean and standard deviation of the corrected pH measurements are

(a)5.64,1.44

(b)5.64,1.32

(c)5.40,1.44

(d)5.40,1.32

(e)5.64,1.20
