Textbook Question

Chapter 9.3, Problem 62E

Ken The same researchers from Exercise 61 wondered how the famous Ken doll measured up to average males and with Australian football players. The table below illustrates some of the results of their research, where each measurement is in centimeters. Assume that the distributions of measurements for the football players and for the reference group follow a normal distribution with the given mean and standard deviation. Source: Sex Roles.

Chapter 9.3, Problem 62E, KenThe same researchers from Exercise 61 wondered how the famous Ken doll measured up to average

(a) Find the probability of Ken’s head size or larger occurring for the reference group and for the football players.

(b) Find the probability of Ken’s neck size or smaller occurring for the reference group and for the football players.

(c) Find the probability of Ken’s chest size or smaller occurring for the reference group and for the football players.

(d) Find the probability of Ken’s upper arm size or smaller occurring for the reference group and for the football players.

(e) Find the probability of Ken’s waist size or smaller occurring for the reference group and for the football players.

(f) Compare the above values and discuss whether Ken’s measurements are representative of either the reference group or football players. Then compare these results with the results of Exercise 61. Any surprises?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

find the zeros of the function algebraically: f(x) = 9x2 - 3x - 2

Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lb
