Assume the null hypothesis was rejected with alpha being 0.05. What happens to the null if alpha gets changed to 0.10?

a) we do not know for sure

b) the null gets rejected for sure

c) the null doesn't get rejected for sure

d) and e) were saying something about a 1% probability that the null gets rejected or doesnt get rejected ( im pretty sure the answer is between a, b or c)

C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.

    QUESTION 49 Assume a researcher published a paper rejecting a null hypothesis at the 1 % level of significance (that is, alpha-001). O a. The finding may not be significant since it was not tested at an alpha level of 0.05 b. You will also reject the null hypothesis at the 5% level of significance since alpha level of 0.01 is a more stringent test ] c. You cannot make any assumptions about the alpha at the 5% level without...
