Math Problem Statement
Rats: A psychologist is designing an experiment in which rats will navigate a maze. Ten rats run the maze, and the time it takes for each to complete the maze is recorded. Following is a boxplot for the simple random sample. Is it reasonable to assume that the conditions for performing a hypothesis test are satisfied? Explain. The boxplot shows that there ▼(Choose one) outliers.
The boxplot shows that there ▼(Choose one) evidence of strong skewness.
We ▼(Choose one) assume that the population is approximately normal.
It ▼(Choose one) reasonable to assume that the conditions are satisfied.
Solution
To address the problem, we need to interpret the information provided by the boxplot and evaluate whether the conditions for performing a hypothesis test are met. Here are the points to consider for each dropdown choice:
- Outliers: Determine whether the boxplot displays any outliers, which are typically indicated by dots or asterisks beyond the whiskers of the boxplot.
- Evidence of Strong Skewness: Assess whether the boxplot suggests skewness. Strong skewness might be indicated by the median line not being centered in the box or by unequal whiskers.
- Assumption about the Population: Determine if it's reasonable to assume that the population from which the sample is drawn is approximately normal. This assumption is crucial for many hypothesis tests, particularly when the sample size is small.
- Reasonableness of Conditions Being Met: Based on the observations from the boxplot, decide if it is reasonable to assume that the necessary conditions for the hypothesis test are satisfied.
Please provide the specific details from the boxplot or any additional observations so we can accurately fill in the choices.
