When one changes the significance level of a hypothesis test from 0.10 to 0.05, which of the following will happen? Check all that apply. A. The chance that the null hypothesis is true changes from 0.10 to 0.05. B. The test becomes more stringent to reject the null hypothesis (i.e., it becomes harder to reject the null hypothesis). C. The test becomes less stringent to reject the null hypothesis (i.e. it becomes easier to reject the null hypothesis). D. It becomes easier to prove that the null hypothesis is true. E. The chance of committing a Type l error changes from 0.10 to 0.05. F. The chance of committing a Type Il error changes from 0.10 to 0.05. G. It becomes harder to prove that the null hypothesis is true.

Perform the test of hypothesis on the following scenarios. A brand of powdered milk is advertised as having a net weight of 250 grams. A curious consumer obtained the net weight of 10 randomly selected cans. The values obtained are 256, 248, 242, 245, 246, 248, 250, 255, 243, and 249 grams. Is there reason to believe that the average net weight of the powdered milk cans is less than 250 grams at 10% level of significance? Assume the net weight is normally distributed with unknown population variance. Note: pls follow the given steps in the photo attached
