To solve for the margin of error:
margin of error = critical value x standard error
To compute for the critical value:
1. compute alpha: α= 1 - (confidence level/100) = 1 - .99 = 0.01
2. Find the critical probability: p = 1 - α/2 = 1 - (0.01/2) = 0.995
3. Look for the z score at the z table, in this case it is 2.58. This is your critical value.
To compute for the standard error, the formula is:
standard error = standard deviation (σ) divided by √n = 1.6 / √420 = 0.0781
Now plug in the following in the formula:
margin of error: 2.58 * 0.0781 = 0.2014 or 0.20
The answer is letter C.
The height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters
From the question,
The average depth of the ocean is about 3688 meters.
Also,
To reach this depth, one would have to stack the tallest tower of the Incheon Bridge in South Korea 16 times.
Now, to determine the height, in meters, of the tallest tower on the Incheon Bridge,
We will divide the average depth of the ocean by 16
That is,
The height of the tallest tower on the Incheon Bridge = 3688 m ÷ 16
∴ The height of the tallest tower on the Incheon Bridge = 230.5 meters
Hence, the height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters

Answer:
112
Step-by-step explanation:
Everything is multiplied by 8
Answer:
0.9 or 90%
Step-by-step explanation:
The probability of shot is 47%
The probability of no shot is 100 -47 = 53%
The dot plot is made from the 10 repeated shots which recorded 25 scores.
The number of dots on the fifth tick is 9 of 10 shots
therefore; 9/10 = 0.9, which 90 in percentage.
