Exercise 3

Table 1

Let start by comparing the mean high temperature for 2022 and 2023.

Table 1. Mean high temperature for 2022 and 2023.

	2022	2023	P-value
Temperature (°C)	21.9 (10.5)	23.4 (9.3)	0.142

Table 2

In addition to measurements of bug and leaf tissue of adult trees, I intended to conduct a similar analysis on entire seedlings. The greenhouse has other ideas…

Table 2. Mean stem diameter and overall height measurements (cm) of three tree seedling species.

	Acer saccharum	Quercus alba	Quercus coccinea	P-value
height (cm)	53.0 (23.3)	11.3 (4.0)	9.2 (2.4)	<0.001
Mean diameter (cm)	0.6 (0.1)	0.3 (0.1)	0.2 (0.0)	<0.001

Table 3

And finally lets take a look to see if there are any differences in LT50 values when comparing before and after last freeze.

Table 3. Mean LT50 for three hardwood tree species

	Acer saccharum	Fagus grandifolia	Liriodendron tulipifera	P-value
Temperature	-11.0 (4.9)	-13.7 (5.2)	-15.2 (3.7)	<0.001
