Answer:

(−14.850850 ; 0.565135)

Step-by-step explanation:

Confidence interval :

Xd ± Tcritical * Sd/√n

Population 1 :30 35 23 22 28 39 21

Population 2 : 45 49 15 34 20 49 36

d = -15,-14,8,-12,8,-10,-15

The mean of d, Xd = Σx / n = - 7.14285714

The standard deviation of the difference, Sd = 10.4948967 (using calculator)

Sample size, n = 7

Tcritical at 90%, df = 7 - 1 = 6

Tcritical = 1.943176

Confidence interval :

- 7.14285714 ± 1.943176 * 10.4948967/√7

Confidence interval :

- 7.14285714 ± 7.7079925

(−14.850850 ; 0.565135)

Answer:x=−y−1

Step-by-step explanation:Let's solve for x.

−y=x+1

Step 1: Flip the equation.

x+1=−y

Step 2: Add -1 to both sides.
