Answer:
Sample mean = 7.1
Margin of error = 0.465
Step-by-step explanation:
Formula for confidence interval is;
CI = x¯ ± zE
Where;
x¯ is sample mean
z is critical value at confidence level
E is margin of error.
z for 99% Cl is 2.58
We are told the CI is 5.9 to 8.3.
Thus;
5.9 = x¯ - 2.58E - - - - (1)
8.3 = x¯ + 2.58E - - - - (2)
Add both equations together to get;
14.2 = 2x¯
x¯ = 14.2/2
x¯ = 7.1
Put 7.1 for x¯ in eq 1 to get;
5.9 = 7.1 - 2.58E
7.1 - 5.9 = 2.58E
E = 1.2/2.58
E = 0.465

Hope it helps!

Answer:
umnim not sure if will be back for that one
Answer:
（-1,-1）（2,0）（4,-20）
Step-by-step explanation:
（-1,-1） = -5 › -6 √
（0,-9） = -9 › -6 ×
（2,0） = 8 › -6 √
（-3,6） = -6 › -6 ×
（4,20） = -4 › -6 √
