Suppose that f(x) is the (continuous) probability density function for heights of American men, in inches, and suppose that f(69) = 0.19. Think carefully about what the meaning of this mathematical statement is.(a) Approximately what percent of American men are between 68.8 and 69.2 inches tall?(b) Suppose F(h) is the cumulative distribution function of f. If F(69) = 0.5, estimate each of:F(68.8) =F(68.6) =

(a) 7.6%

(b) 46.2%    42.4%

Step-by-step explanation:

(a)According to the definition of Continuous probability distribution

⇒ 0.19 × 0.4 = F(69.2) - F(68.8)

⇒ F(69.2) - F(68.8) = 0.076

⇒ 7.6%

(b) Given F(69) = 0.5

⇒ 0.19 × 0.2 = F(69) - F(68.8)

⇒ F(68.8) = 0.5 - 0.038 = 0.462

⇒ 46.2%

⇒ 0.19 × 0.4 = F(69) - F(68.8)

⇒ F(68.8) = 0.5 - 0.076 = 0.424

⇒ 42.4%

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
