The coefficient of y in this expression is 3
What number can you divide both the divisor and denominator by?
i see that 12 and 126 are divisible by 1, 2, 3, and 6
we're going to choose the biggest number we can divide by (which is 6)
12/6=2 / 126/6=21
the answer would be 2/21 because there is no other number (other than 1) that you could divide these both into

Answer:
(0.869, 12.33104)
Step-by-step explanation:
N1 = 110
N2 = 225
S1 = 24.8
S2 = 25.8
Bar x1 = 169.9
Bar x2 = 163.3
Difference in mean = 169.9 - 163.3 = 6.6
We use the z score
Alpha = 0.05
Z critical value at this alpha level = 1.96
We find standard error
√s1²/n1+s2²/n2
= √(24.8²/110 + 25.8²/225)
= 2.9239
Confidence interval
6.6 +-1.96(2.924)
(6.6-5.73104, 6.6+5.73104)
= (0.869, 12.331)
