number of concurrent deviations was found to be 6, then the value of p is
(a) 10
(b)9
(c) 8
(d)none of these​

Answer 1

Step-by-step explanation:

Given 24. The coefficient of concurrent deviation for p pairs of observations was found to be 1/√3 number of concurrent deviations was found to be 6 then the value of p is

(a) 10

(b)9

(c) 8

(d)none of these​

• Given coefficient of concurrent deviation is given by R = ±√2 c – m / m
• Now m = p – 1 and c = 6 and R = 1/ √3
•        So 1/√3 = √2 x 6 – (p – 1) / p -1
•            1/√3 = √12 – p + 1 / p – 1
•   Squaring both sides we get
•       1/3 = 13 – p / p – 1
• Or p – 1 = 39 – 3p
• 4p = 40
•           Or p = 40 / 4
•         Or p = 10  pairs

Answer 2

Answer:

10

Step-by-step explanation:

Given:

r = 1/√3

c = 6

r = +-√(2c - m)/m

1/√3 = √(2*6 - m)/m

Squaring on both sides

1/3 = (12 - m)/m

m = 36 - 3m

4m = 36

m = 9

p = 9 + 1

p = 10
