Can you tell me if my answers are correct?
![Twelve different video games showing alcohol use were observed. The duration times of alcohol use were recorded, with the times (seconds) listed below. Assume that these sample data are used with a 0.10 significance level in a
test of the claim that the population mean is greater than 85 sec. If we want to construct a confidence interval to be used for testing that claim, what confidence level should be used for a confidence interval? If the confidence interval
is found to be 22.2 sec< u< 179.7 sec, what should we conclude about the claim?

The confidence level should be 90 %.
(Type an integer or a decimal. Do not round.)
What should we conclude about the claim?
The given confidence interval
contains
the value of 85 sec, so there
is
sufficient evidence to support the claim that the mean is greater than 85 sec.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5eb61cca-0703-4b10-8fae-b450466856ff%2Ffd81787e-0643-4dcb-a239-d9a271c0b81b%2F5n3i9o_processed.png&w=3840&q=75)
