Answer:
6720
Step-by-step explanation:
The writing 8P5 represents the number of permutations of 8 elements taken 5 at a time.
<u></u>
<u>First Method</u> :
8P5 = 8 × 7 × 6 × 5 × 4
= 6720
<u>Second Method</u> :
Answer:
32x^5-80x^4+80x^3+32x^2+10x-1
Answer:
The conclusion is True
Step-by-step explanation:
Solution:
- The standard deviation of company s1 = 0.035
- The standard deviation of company s2 = 0.062
- Null Hypothesis : s1^2 = s2^2
- Alternate hypothesis : s1^2 < s2^2
- Criteria to reject Null: M > M_a ( 12 - 1 , 12 - 1 )
- From Tables, M > 2.82
- M - statistics value M = s2^2 / s1^2
- M = (0.062 / 0.035)^2 = 3.14
- M = 3.14 > 2.82 ... Criteria of rejection is met
- Null Hypothesis must be rejected at level of significance a = 0.05
- p value, 1 - 0.965 = 0.035 < 0.05 ( Significance Level )
- The conclusion is True
