Im pretty sure its obtuse
The effect of decreasing the alpha level from 0.05 to 0.01. it decreases the probability that the sample will fall into the critical region, it decreases the probability of a Type I error, and it decreases the size of the critical region.
Therefore, the answer is that all of other options are results of decreasing alpha.
Remark
The order is not quite correct.
- 7 + (-11 * 5 - - 7) ÷ - 6
The - - 7 becomes a plus
- 7 + (- 55 + 7) ÷ -6
This is where the real problem is. -55 + 7 goes down. This gives - 48
- 7 + [( - 48) ÷ - 6]
You do the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.
-7 + (8)
The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.
