Use the formula to find the standard error of the distribution of differences in sample means, x¯1-x¯2 . Samples of size 110 fro

Volgvan

Answer:

2.104

Step-by-step explanation:

Data provided in the question:

For sample 1,

n₁ = 110

μ₁ = 94

s₁ = 14

For sample 2,

n₂ = 85

μ₂ = 72

s₂ = 15

Now,

Standard error = $\sqrt{\frac{s^2_1}{n_1}+\frac{s^2_2}{n_2}}$

or

Standard error = $\sqrt{\frac{14^2}{110}+\frac{15^2}{85}}$

or

Standard error = √4.43

or

Standard error = 2.104

2^-2 = 1/2^2

so: (1/2^2)*(12*3)-5^3

simplify: (1/4)*36-125

36*(1/4) = 36/4 so: 9-125

subtract: -116
