Gribbles are small, pale white, marine worms that bore through wood. While sometimes considered a pest since they can wreck wood
Stells [14]

<u>Answer with explanation:</u>

As per given , we have

A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72.

i.e. n= 50

Degree of freedom = n-1=49

\overline{x}=3.1\ mm

s=0.72\ mm

The point estimate of the population mean is equals to the sample mean.

i.e. The best estimate for the length of gribbles= 3.1 mm

Also, population standard deviation is unknown , then the confidence interval would be :

E=t_{\alpha/2, df}\dfrac{s}{\sqrt{n}}

For df= 49 and significance level of 0.05 , the t- value (using t-distribution table) would be :

t_{0.05/2, 49}=t_{0.025, 49}= 2.010

Now, Margin of error : E=(2.010)\dfrac{0.72}{\sqrt{50}}

=0.204664986747\approx0.20

95% confidence interval : (\overline{x}-E,\ \overline{x}+E)

i.e.\ (3.1-0.20, 3.1+0.20)=(2.90,\ 3.30)
