Identify the Type I Error or Type II Error as Indicated

question 61

Multiple Choice

Identify the Type I error or Type II error as indicated.
-In the past, the mean running time for a certain type of flashlight battery has been 8.9 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the
Mean running time has increased as a result. The hypotheses are: $$\begin{array} { l } \mathrm { H } _ { 0 } : \mu = 8.9 \text { hours } \\\mathrm { H } _ { \mathrm { a } } : \mu > 8.9 \text { hours }\end{array}$$
Identify the Type I error.

• A)Reject the claim that the mean running time is 8.9 hours when actually the mean running time is greater than 8.9 hours.
• B)Reject the claim that the mean running time is 8.9 hours when actually the mean running time is 8.9 hours.
• C)Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is greater than 8.9 hours.
• D)Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is 8.9 hours.

Definitions:

A-B Design

A basic experimental design consisting of a baseline (A) phase followed by a treatment (B) phase, used to evaluate the effect of an intervention.

Intervention

Strategies or actions taken to improve a situation or problem, often used in the context of behavioral or medical treatment.

Behavior Change

A modification in an individual's behavior patterns, attitudes, or actions.

Multiple Baseline Design

A method of graphing behavioral observations that provides a way to evaluate the effectiveness of an intervention when a reversal design is not desirable. A multiple baseline design permits recording and analyzing behavioral observations from three variables: (1) two or more behaviors associated with one student in a single setting, (2) two or more students exhibiting the same behavior in a single setting, and (3) two or more settings in which one student is exhibiting the same behavior.
