The answer is 12·08542
Explanation:
Answer Run Test
Ho: Arrival is in random manner.
H1: Arrival is not in random manner
No. of males (M) = 23 (2)
No of female (F) (72) = 27
Since n, & my are 7 10 we use z fest.
for £=0·05 Z=1.96
No. of Runs (R) = 24.
How
R = E(R) = 2₁nz +1
= - 223)(27) 297423 1242 50
= 25.84
= $27,72 (21₁₂-11-12)
= -2(23) (27) (2123) (27) — 23-27]
(23-127)2 (23+27-1)
1242 (1992)
502 (49)
= 3.48
= 12·08542
