Answer:
9.72
Step-by-step explanation:
s1 = 10.6383 ; s2 = 5.21289
x1 = 147.583 ; x2 = 136.417
n1 = 12 ; n2 = 12
df1 = n1 - 1 = 12 - 1 = 11
df2 = n2 - 1 = 12 - 1 = 11
The test statistic :
(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]
Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)
Sp² = ((11*10.6383) + (11*5.21289)) / 22 = 7.926
Test statistic, T* :
(147.583 - 136.417) / √(7.926 * (1/12 + 1/12))
11.166 / √(7.926 * (1/6)
11.166 / √1.321
11.166 / 1.1493476
T* = 9.7150766
Test statistic = 9.72
1. A = s² + 1/2bh
A = (x)² + 1/2(yz)
A = x² + 1/2y1/2zft²
2. A = s² + 1/2bh
A = (7)² + 1/2(3)(2)
A = 49 + 1/2(6)
A = 49 + 3
A = 52ft²
Answer:
the answer is 92 bags.
167x11=1837
1837÷20=91.85....or 92 bags
