Does the light condition affect the mean of your variables? State the null and alternate hypothesis for your variable and perform an ANOVA test by completing the table and stating your conclusion. ??: Ha df MS p-value Factor(Group) Error d. State your conclusion. Are the means significantly different for this variable among the three light conditions? (use alpha, a -0.05)Explanation / Answer
c] For body mass gain
H0: mu1 = mu2 =mu3 Vs H1: Atleast one mu is different
One-way ANOVA: response versus factor
Factor Information
Factor Levels Values
factor 3 1, 2, 3
Analysis of Variance
Source DF Adj SS Adj MS F-Value P-Value
factor 2 35.23 17.62 1.62 0.219
Error 25 272.67 10.91
Total 27 307.91
d] Here pvalue = 0.219 > alpha = 0.05
Fail to reject H0. Therefore the means are not significantly different for this variable among the three light conditions.
c] For Calories
H01: mu1 = mu2 =mu3 Vs H11: Atleast one mu is different.
One-way ANOVA: response2 versus factor
Factor Information
Factor Levels Values
factor 3 1, 2, 3
Analysis of Variance
Source DF Adj SS Adj MS F-Value P-Value
factor 2 7238 3619.22 39.01 0.000
Error 25 2319 92.77
Total 27 9558
d] Here pvalue = 0.00 < alpha = 0.05
Reject H0. Therefore the means are significantly different for this variable among the three light conditions.
