At the same time each day, a researcher records the temperature in each of three greenhouses? The table shows the temperatures in degrees Fahrenheit recorded for one week. $\begin{array}{c|c|c}
\text { Greenhouse \#1 } & \text { Greenhouse \#2 } & \text { Greenhouse \#3 } \
\hline 73 & 71 & 67 \
72 & 69 & 63 \
73 & 72 & 62 \
66 & 72 & 61 \
68 & 65 & 60 \
71 & 73 & 62 \
72 & 71 & 59
\end{array}$ What type of test would you use to test the claim that the average temperature is the same in
Each greenhouse at a 0.05 significance level?
A) One-way ANOVA
B) Two-way ANOVA
C) Goodness-of-Fit
D) Test of Independence
