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

A one-way ANOVA is used to compare the means of three or more independent groups (in this case, the temperatures in the three greenhouses) to see if there is a significant difference among them.
