Answer:
7627.36
Step-by-step explanation:
95342 * 8% = 7627.36
Answer:
yes
Step-by-step explanation:
u={1,2,3,4,5,6,7,8,9}
m={2,4,6,8}
N={1,2,4,8}
O={2,4,6,8}
Now
M intersection (N intersection O) = (M intersection N) intersection O
or , {2,4,6,8} intersection {2,4,8} ={2,4,8}
intersection {2,4,6,8 }
:. {2,4,8} ={2,4,8}
Solution :
Let x be student will be left handed
P = 0.09
Using the normal approximation to binomial distribution,
a). n = 108,
μ = np = 9.72


= 2.9741
Required probability,
P(x=8) = P(7.5 < x < 8.5)


Using z table,
= P(z<-0.41)-P(z<-0.75)
= 0.3409-0.2266
= 0.1143
b). P(x=12) = P(11.5 < x < 12.5)


Using z table,
= P(z< 0.94)-P(z< 0.60)
= 0.8294 - 0.7257
= 0.1006
