Answer :

To determine whether a typical adult hematocrit value is [tex]$45\%$[/tex], consider the following:

1. Definition: Hematocrit is the ratio of the volume of red blood cells to the total volume of blood. It is usually expressed as a percentage.

2. Typical Value: Research data suggest that an average or typical adult hematocrit value is around [tex]$45\%$[/tex].

3. Verification: The given hematocrit value is indeed [tex]$45\%$[/tex], which matches the typical value we identified.

After comparing the given hematocrit value with the expected typical value, we can conclude that the statement is:

True

The typical adult hematocrit value is indeed [tex]$45\%$[/tex].
