Nitella [24]

Answer: 1.2703

Step-by-step explanation:

Given : Sample size : n= 17, which is a small sample (n<30), so we use t-test.

Significance level : \alpha:1-0.90=0.1

Then , Critical value : t_{n-1,\alpha/2}=t_{16, 0.05}\pm1.745884

Standard deviation: s=3\text{ inches}

The formula to find the margin of error : -

E=t_{n-1,\alpha/2}\dfrac{s}{\sqrt{n}}\\\\\Rightarrow\ E=(1.745884)\dfrac{3}{\sqrt{17}}\\\\\Rightarrow\ E=01.27031720154\approx1.2703

Hence, the error bound (EBM) of the confidence interval with a 90% confidence level.=1.2703
