Answer:
95% confidence level should be used for a confidence interval.
The given confidence interval contains the value of 85 sec, so there is not sufficient evidence to support the claim that the mean is greater than 85 sec.
Step-by-step explanation:
0.05 significance level
1 - 0.05 = 0.95
0.95*100% = 95%
This means that a 95% confidence level should be used for a confidence interval.
Confidence interval is found to be −1.8 sec<μ<213.5 sec, what should we conclude about the claim?
Contains the value of 85 sec, thus there is not sufficient evidence to support the claim that the mean is greater than 85 sec.

Answer:
<h2><u>0.384</u></h2>
Step-by-step explanation:
By Pythagoras Theorem,
OM = √(4² + 3²) = √(16 + 9) = √25 = <u>5</u>
And,
OL = √(12² + 5²) = √(144 + 25) = √169 = <u>13</u>
Now,
sin L = 
= 
= <u>0.384</u>
4 293/1,000 or 4239/1000 or even four and two hundred ninety-three thousandths. I hope this helps!
