Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is



The unit rate is the slope
y=mx+b
m=slope
b=y intercept
equation is y=7x
slope=7
y intercept=0
slope=unit rate because if you use 5 gasoline then you go 5 times 7 miles or 35 miles
The unit rate is 7
Hope I helped :)
