Five different paints are marketed as having the same drying time. To verify the manufacturer's claim, the dry times of paints were measured in seconds and recorded in the uploaded DATA. Test the claim that the drying times are equal at α = 0.05. 

Question 5 options:

The pvalue of 3.73E-20 indicates that the data provide significant evidence against H0. H0 is rejected at α = 0.05. Action is required.


The pvalue of 4.2E-22 indicates that the data provide significant evidence against H0. H0 is rejected at α = 0.05. Action is required.


The F test statistic 1.338 does not exceed the critical value 2.579 and indicates that the data provide insignificant evidence against H0. H0 is not rejected at α = 0.05.


The F test statistic 123.4 exceeds the critical value 2.579 and indicates that the data provide significant evidence against H0. H0 is rejected at α = 0.05.  Action is required.


The F test statistic 0.535 does not exceed the critical value 2.579 and indicates that the data provide insignificant evidence against H0. H0 is not rejected at α = 0.05.


None of the answers match my ANOVA.

Based on what is readable:

Here are the initial drying times (seconds) for the paints:
1. Paint 1: 713, 705, ...
2. Paint 2: 689, 717, ...
3. Paint 3: 705, 699, ...
4. Paint 4: 657, 656, ...
5. Paint 5: 702, 705, ...

To properly test the claim using ANOVA at \( \alpha = 0.05 \), I need to organize the data into columns for proper statistical testing. Would you like me to refine the extraction or manually input the dataset for precise results? Let me know!

Five different paints are marketed as having the same drying time. To verify the manufacturer's claim, the dry times of paints were measured in seconds and recorded in the uploaded DATA. Test the claim that the drying times are equal at α = 0.05.

Explore the statistical analysis of drying times for five different paints using ANOVA at α = 0.05. This example demonstrates hypothesis testing, the F-statistic formula, and critical value comparisons to validate the manufacturer's claim.
