I need a clarification of the sentence included in bold. Is that the error type II? The exercise is:

The weight of a plate is a continuous random variable, normally distributed with $\mu=330$ gr. and standard deviation 5 gr.

Supposing that we have a sample of 25 plates with a mean weight of 333 gr., sample variance of 25 gr. and a significance level of 10%, check the hypothesis that $μ=330$ or $μ>330$.

What is the maximum significance level that the null hypothesis is not rejected?
