Question

A random sample of 25 executives from companies with assets over $1 million was selected and asked for their annual income and level of education. The following Excel printout summarized the results: Since the p-value is small (0,000779, smaller than 1% significance level, there is a significant difference in the incomes of these 3 groups. Since the p-value is small (0,000779, smaller than 1% significance level, there is strong evidence to suggest that at Since the p-value is small (0,000779, smaller than 1% significance level, there is no Since the p-value is small (0,000779, smaller than 1% significance level, there is strong evidence to suggest that the three groups with different levels of education do not Since the p-value is 0,001, there is a 10% change of these results happening when there is no significant difference in the incomes of these three groups.

Explanation / Answer

The p-value of the test is 0.000779.

Since p-value is less than 0.01 so we reject the null hypothesis.
