A lumber milling process traditionally ends up with 28% of its planks in "choice" condition, meaning suitable for furniture rather than general construction. A change in the milling procedure was tried for a batch of 60 planks, and this produced 26 in "choice" condition. Is this a significant change?
1. State the null and experimental hypothesis
Decide how unlikely your data has to be assuming the null is true for you to reject the null in favor of the experimental hypothesis
To test the hypothesis, calculate a critical ratio
What distribution does it follow?
What is the critical value at your chosen alpha level?
Make your statistical decision (retain/reject) the null based upon your chosen alpha level.
State your conclusion in a sentence that relates your statistical decision to the study
Help please, i really need a detailed explanation to understand how to do this
