Quizplus · Accepted Answer

Alan will use the p-value to determine the significance level of the results. The p-value is the probability of obtaining the observed data or more extreme data, assuming the null hypothesis is true. A small p-value indicates strong evidence against the null hypothesis, suggesting that the observed relationship between background music and sales is significant. A commonly used significance level is 0.05, meaning that if the p-value is less than 0.05, the results are considered statistically significant.
