Question 19 \( 1.75 \mathrm{pts} \) If we reject a nul hypothesis, that is to syy we reject the notion that tao population means ane the same, and we work at the 0.05 level of significance: there is a 95 in 100 chance that we rade a correct decision the odth are 5 to 1 we made a bad decinion.

Step 1
Secondly, working at the 0.05 level of significance means we are willing to accept a 5% chance of making a Type I error, which is rejecting the null hypothesis when it is actually true. Show more…

If you wish to test the claim that the mean of the population is 100, the appropriate null hypothesis is
David N.
Setting your alpha at .05 means there is a 5% chance you will reject the null hypothesis even though it is actually true. Suppose we are conducting a study where making this type of error could lead to severe consequences. If we wanted to be more conservative and set our alpha at .01 (1% chance) for a one-tailed test then what should our new cutoff score be? 2.33 .01 .496 3.7
Juan N.
Suppose that we reject a null hypothesis at the 5% level of significance. Without knowing the p-value for the test, for which of the following significance levels would we also definitely reject the null hypothesis? 1% 2% 10% None of the above.
