<span>Yes, there will be a total of 6 distance markers that are placed at the same location as one of the other items. At 25% through the race there will be a water station and distance marker. At 40% through the race there will be another water station and distance marker. At 50% there will be a viewing station and two distance markers. At 60% there will be a water station and a distance marker. At 80%, another water station and distance marker. And finally, at 100% through the race there will be a water station, viewing station and two distance markers.</span>
Given :
Number of methods, k = 3
Number of the observations, n = 30
Degrees of freedom Treatment = k - 1
= 3 - 1 = 2
Degrees of freedom for error = n - k
= 30 - 3 = 27
= 10800 - 4560
= 6240
Source variation Sum of square Degrees of freedom Mean square F
Treatment 4560 2 2280 9.8653
Error 6240 27 231.11111111
Total 10800
The critical value of F for the 0.05 sig level and df (227) is 3.354
Since the test stat > critical value of F, so we reject null hypothesis and state that there is a significant difference in the means of the three assembly methods.
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
If we want to convert any percent to a decimal, you want to think of the percent as a ratio of the percent to 100 or the percent divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so we will move the decimal point 2 places to the right to get our answer.
Let's look at an example.
<em>Write the following percent as a decimal</em>. 9%
We know that we can change a percent to a decimal by simply moving the decimal point 2 places to the left.
So in this problem, to write 9% as a decimal, we simply move the decimal point 2 places to the left and fill in the missing position with a zero.
So 9% can be written as the decimal <em>.</em>09 or 0<em>.</em>09.
A common mistake in this problem is to write 9% as the decimal 0.9 but remember to move the decimal point 2 places to the left so our answer is 0<em>.</em>09.
The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15
