A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.10 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute? A. Determine the test statistic. (Round to two decimal places as needed.) B. Determine the P-value.

Question
A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.10 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute?
A. Determine the test statistic.
B. Determine the P-value.
(Round to three decimal places as needed.)
Transcribed Image Text:**Data Set**
The following series of numbers represents a data set that can be used for statistical analysis:
- 72
- 81
- 42
- 64
- 45
- 25
- 61
- 63
- 64
- 46
- 62
- 70
- 90
- 87
- 63
**Usage**
This data can be applied in various educational contexts, such as teaching statistical concepts like mean, median, mode, range, and standard deviation. The values can also be used in exercises related to data visualization, such as creating histograms, bar charts, or box plots.
**Visualization Tips**
For visual learners, consider using a bar graph to represent the frequency of each number in the set. This can help highlight the mode and observe any patterns or trends in the data. Using a line graph might help illustrate changes or trends if these numbers represent a time series or sequential data.
**Data Analysis Questions**
1. What is the mean of the data set?
2. Identify the mode(s) of the data set.
3. Calculate the median value.
4. Determine the range of the values.
5. Discuss how the data might be interpreted in a real-world context.
