Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error =
Substituting the values in above equation
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
2x+43+2x-3=180
4x+40=180
4x=140
x=35
