Kaladin wonders whether the strength of a bridge depends on the weather. He tests bridge strength under four different types of weather patterns. Based on the data below and assuming normality with equal variances fill out the ANOVA table and finish the hypothesis test. Sunny Cloudy Stormy Hurricane 48 days Average 146.2 kN/m2 Std deviation 9.2 kN/m2 57 days Average 145.3 kN/m2 Std deviation 11.5 kN/m2 37 days Average 149.4 kN/m2 Std deviation 13.6 kN/m2 50 days Average 142 kN/m2 Std deviation 12.4 kN/m2 To solve this you'll need the overall average. What is it (to one decimal)? Use three decimal places in the table DF SS MS F Groups Error Total

Kaladin wonders whether the strength of a bridge depends on the weather. He tests bridge strength under four different types of weather patterns. Based on the data below and assuming normality with equal variances fill out the ANOVA table and finish the hypothesis test.

Sunny Cloudy Stormy Hurricane
48 days
Average 146.2 kN/m2
Std deviation 9.2 kN/m2		 57 days
Average 145.3 kN/m2
Std deviation 11.5 kN/m2		 37 days
Average 149.4 kN/m2
Std deviation 13.6 kN/m2		 50 days
Average 142 kN/m2
Std deviation 12.4 kN/m2



To solve this you'll need the overall average. What is it (to one decimal)?
