Answer:
[tex]9.35 \le M \le 9.45[/tex]
Step-by-step explanation:
Given
[tex]M = 9.4[/tex] to 1 d p
Required
The error interval
The error interval is represented as:
[tex]Lower \le M \le Upper[/tex]
Where
[tex]Lower = M - 0.05[/tex]
[tex]Upper = M + 0.05[/tex]
So, we have:
[tex]Lower = M - 0.05[/tex]
[tex]Lower = 9.4 - 0.05[/tex]
[tex]Lower = 9.35[/tex]
[tex]Upper = M + 0.05[/tex]
[tex]Upper = 9.4 + 0.05[/tex]
[tex]Upper = 9.45[/tex]
Hence, the error interval: [tex]Lower \le M \le Upper[/tex] is:
[tex]9.35 \le M \le 9.45[/tex]
