Use the formula to find the standard error of the distribution of differences in sample means, x¯1-x¯2 . samples of size 110 from population 1 with mean 94 and standard deviation 14 and samples of size 85 from population 2 with mean 72 and standard deviation 15 round your answer for the standard error to

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 =

or

Standard error =

or

Standard error = √4.43

or

Standard error = 2.104
