In a test of statistical significance, what does the p-value tell us?

A. if the null hypythesis is true
B. if the alternative hypothesis is true
C. the largest level of significance at which the null hypothesis can be rejected
D. the smallest level of significance at which the null hypothesis can be rejected.

Please explain exactly what the p-value is as I'm having trouble understanding it. thanks

Suppose that in a certain hypothesis test the null hypothesis is rejected at the .10 level; it is also rejected at the .05 level; however it cannot be rejected at the .01 level. The most accurate statement that can be made about the p-value for this test is that: p-value = 0.01. p-value = 0.10. 0.01 < p-value < 0.05. 0.05 < p-value < 0.10.

In a two-tailed hypothesis test of the mean using a 0.05 level of significance, researchers calculated a p-value of 0.03. What conclusion can be drawn? The alternative hypothesis should be rejected because the p-value is so small. The null hypothesis is true because the p-value is less than the level of significance. The alternative hypothesis is 3% likely to be true. The null hypothesis should be rejected because the p-value is less than the level of significance. 1.The alternative hypothesis...

True or False When using Levene's test for ANOVA, the p-value should not indicate statistical significance (e.g. p<.05) because the null hypothesis states that the variance of the dependent variable is the same across comparison groups.
