Answer: 12 hours and 24 Minutes
Step-by-step explanation:
7*60 = 420
810/420 = 1.9285
93- 100 = 53-60
subtract 40 from 93.
1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
Solution :
<u>Sample size</u> <u> Sample mean</u> <u> Sample S.D.</u>
Sample 1 
Sample 2 
= 60
Therefore, significance level, α = 0.1
Critical value, t* = 1.6706
So, the margin of error, 
= 559.9896
Lower limit, 
Upper limit, 
Therefore 90% C.I. is (44402.0104, 55597.9896) or 
The author of Passage 1 indicates that becoming adept at using the Internet can undermine the ability to think deeply.
