Answer:
Confidence interval = 48±4
Step-by-step explanation:
Given:
Mean X = 48
Standard deviation sd = 14.1
Computation:
Z table value of 90% = 1.645
Total number n = 33
Computation:
Margin of error M.E = Z[sd/√n]
Margin of error M.E = 4 approx.
Confidence interval = 48±4
Answer:

Answer:
62.8% OR 0.628
Step-by-step explanation:
11 hours playing video games
11 hours on the Internet
11 + 11 = 22
5 hours of free time each day
7 days in a week
5 x 7 = 35
22/35 hours are spent
That is 0.62857142857 or I just mathmatically rounded to 0.628
0.628 into a fraction is 62.8%
The speed of train is 11.304 meters per second.
Further explanation:
Let us define speed first.
"Speed is the rate at which something is moving or changing position"
Speed is denoted by s. The formula for speed is:
Here,
d = 26 meters
t = 2.3 sec
Putting the values in the formula:
The speed of train is 11.304 meters per second.
