Answer: Water isn't wet by itself, but it makes other materials wet when it sticks to the surface.
Explanation:
Liquid water is not itself wet but can make other solid materials wet. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material. Cohesive forces are also responsible for surface tension.

What is the critical value t' for constructing a 90% confidence interval for a mean from a sample size of
n=18 observations?
Answer:
[tex]t^* = 1.740[/tex]
Explanation:
Given
[tex]n = 18[/tex] --- sample
[tex]CI= 90\%[/tex] --- confidence interval
Required
Determine the critical value
Start by calculating the degrees of freedom (df)
[tex]df = n - 1[/tex]
[tex]df = 18 - 1[/tex]
[tex]df = 17[/tex]
Next, calculate the significance level
[tex]\alpha = \frac{1 - CI}{2}[/tex]
This gives:
[tex]\alpha = \frac{1 - 90\%}{2}[/tex]
Express percentage as decimal
[tex]\alpha = \frac{1 - 0.90}{2}[/tex]
[tex]\alpha = \frac{0.10}{2}[/tex]
[tex]\alpha = 0.05[/tex]
Next, we look at the t table at
[tex]df = 17[/tex]
and
[tex]\alpha = 0.05[/tex]
We have the critical value to be:
[tex]t^* = 1.740[/tex]
