Question

1. An experiment was run at two different temperature levels, as indicated in the table below.

Data:

Temp	y1	y2	y3	y4
70	2.2	2.8	3.2	3.6
90	5	4.6	5.8	5.4

1. Excel to summarize a Single Factor ANOVA, use alpha = 0.05
2. State and test the Hypothesis using the F statistic
3. Are the means equal

Answer 1

Anova: Single Factor
SUMMARY
Groups	Count	Sum	Average	Variance
70	4	11.8	2.95	0.356667
90	4	20.8	5.2	0.266667
ANOVA
Source of Variation	SS	df	MS	F	P-value	F crit
Between Groups	10.125	1	10.125	32.48663	0.001261	5.987378
Within Groups	1.87	6	0.311667
Total	11.995	7

p-value = 0.001261 < 0.05

we reject the null hypothesis

c) there is evidence that the means are not equal
