g A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 19 students and observed that they had a mean of 10.4 hours with a variance of 1.44. Is there evidence at the 0.025 level that the technique lengthens the training time

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

-2 is the right

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
