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

Stells [14]

Answer with explanation:

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 : $(\overline{x}-E,\ \overline{x}+E)$

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

GIVING BRAINLIEST IF YOU DO IT CORRECT

We use the word argument to refer to a series of reasons given to support a claim. The claim being supported is the conclusion. The reasons given to accept the conclusion are called premises. Analyzing an argument means identifying its premises and conclusion.

Hope this helps! God bless you, have a good day~!
