1a) no it would be 54
1b) yes
1c) yes
1d) no it would be 40
1e) yes
hope this helped
Answer:
6 samples
Step-by-step explanation:
Given :
Sample size, = n
Standard deviation, = 6000
Margin of Error = 2000
Confidence interval, α = 95%
Zcritical at 95% = 1.96
n = (Zcritical * σ) / margin of error
n = (1.96 * 6000) /2000
n = 11760 / 2000
n = 5.88
n = 6 samples
divide by 2 on both sides.
3/2
x=1.5
Required algebraic expression is 3/z
