Answer: 0.9577
Step-by-step explanation:
Formula for margin of error (E):
, where p = sample proportion, n =sample space, z* critical z-value.
Given: n= 200
Critical value for 97% confidence level = 2.17
Margin of error (E) =
Hence, the margin of error for a 97% confidence interval = 0.9577
Answer:
The answer is 103
Step-by-step explanation:
The given expression is:
300-7[4(3+5)]+3 to the 3rd power
3 to the 3rd power means 3^3
Therefore,
300-7[4(3+5)]+3^3
First we will solve the round bracket and find the cube
300-7[4(8)]+27
Now we will solve square bracket
300-7[32]+ 27
300-224+27
76+27
103
Thus the answer we get is 103....
