Ten Percent of the Population Is Left-Handed $\mathrm { P } ( \mathrm { x } \geq 15 )$

question 52

Multiple Choice

Ten percent of the population is left-handed. A class of 1800 students is selected. Convert the binomial probability $\mathrm { P } ( \mathrm { x } \geq 15 )$ to a normal probability by using the correction for continuity.

• A) \(\mathrm { P } ( \mathrm { x } \geq 14.5 )\)
• B) \(\mathrm { P } ( \mathrm { x } < 14.5 )\)
• C) \(\mathrm { P } ( \mathrm { x } \leq 15.5 )\)
• D) \(\mathrm { P } ( \mathrm { x } \geq 15.5 )\)

Definitions:

Coefficient Of Skewness

A measure quantifying the degree of asymmetry in the distribution of a dataset, indicating how much it deviates from a normal distribution.

Symmetry

A characteristic of shapes or patterns that exhibit proportionate similarity between parts, often mirrored around a central axis.

Coefficient Of Skewness

A statistical measure that quantifies the asymmetry of a distribution around its mean, indicating if the distribution leans to the left or right.

Skewness

A measure of the asymmetry of the probability distribution of a real-valued random variable, indicating how much the distribution leans to one side of the mean.
