P value threshold

I came across an example where "the p-value of 0.33 is high, thus xyz will fail to reject null hypothesis.

In the absence of a significance level to compare with, what would be a reasonable demarcation of p value to conclude as above?

Generally, alpha (significance level, DIFFERENT from pvalue) is between .1 and .01, sometimes it can be higher (but this is outside the scope of the curriculum). If I recall, the test guideline would be to assume .05 as the alpha level unless otherwise stated.

Thanks a lot

Glad to be helpful!
