Step-by-step explanation:
Answer: option B
Step-by-step explanation: at alpha level of 5% for a two tailed test, the critical value is +1.96 and -1.96
At alpha level of 1% for a two tailed test, the critical value is +2.576 and -2.576
Relating z = 2.77 with these critical values, we can see that at 5% level of significance, z = 2.77 is greater than +1.96 which falls in the rejection region.
Also at 1% level of significance, we can see that z = 2.77 is greater than 2.576 which also falls in the rejection region.
Answer: the answer is D.
x/-2 - 17 = -7 (subtract both sides by -17)
x/-2 = 10 (multiply both sides by -2)
x = -20
