Answer:
The minimum sample needed to provide a margin of error of 3 or less is 52.
Step-by-step explanation:
The confidence interval for population mean (<em>μ</em>) is:
The margin of error is:
<u>Given:</u>
MOE = 3
<em>σ </em>= 11
The critical value for 95% confidence interval is: 
**Use the <em>z</em>-table for critical values.
Compute the sample size (<em>n</em>) as follows:
Thus, the minimum sample needed to provide a margin of error of 3 or less is 52.
the answer is three look where it says 4-1 is 3
Answer:
I am pretty sure the answer is 498.
Step-by-step explanation:
You have to solve the parentheses first. So,
9(7 (14-6) -3 x 2)
63 (8) -6)
63(8)-6
63(8) = 504
504-6 = 498
please let me know f this is correct :)
