Answer:
8.5
Step-by-step explanation:
exemptions married : 4000
2 dependents 2* 2000 = 4000
8000 off his salary
58980-8000=50980
50980* percent =2549
percent = 2549/50980
percent =.05
percent = 5%
the third and forth option:
9.2 × 10-9
3.4 × 10-10
Answer:
n is 192
Step-by-step explanation:
Given data
Cl = 95%
interval = 0.2
to find out
what value n
solution
we have interval = 0.2
so interval has width at most is 0.5 so
margin of error E = 0.2 /2 = 0.1
and we know Z value for 95% Cl is 1.96 from z table
so sample n = Z²/E² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 1.96²/0.1² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 192.08
so n is 192
