question 316

Multiple Choice

Solve the problem.
-A spinner has five regions numbered 1 through 5. If the spinner is spun 100 times, we would expect about 20 of the outcomes to be Region 1. It can be determined that the spinner is unbalanced if x, the number of outcomes that result in Region 1, satisfies $\left| \frac { x - 20 } { 4 } \right| \geq 1.645$ . Describe the number of outcomes that determine an unbalanced spinner that is spun 100 times.

• A) Fewer than 14 or more than 26 outcomes
• B) Fewer than 17 or more than 29 outcomes
• C) Between 14 and 26 outcomes
• D) Between 17 and 29 outcomes
