7. The following values were measured at 1- metre intervals. Plot and apply simple 3-point and 5-point filters. What are the max
imum and minimum values of the unfiltered and two filtered data sets? What are the most obvious wavelengths in each case? –3, 2, 1, 4, 0, 4, –1, 3, 0, 1, –4, 0, –4, –1, –4, 1, 0, 2, 4.
Maxima and minima are+ 4,-4; 2.67,-3; 2.2, -2.6, respectively.
The first and most noticeable wavelengths are 2 m and around 15 m however the 3-and 5-point filters gradually decrease the amplitude of the 2-m wave-length.
By doing so, they provide the illusion that the payments are cheaper then 1000 dollars, because 50 looks very small, when in reality it's $100 more then what the mattress is actually worth.
There are five separate points. One represents students who made more than 13 baskets. The other four represent students who made 13 or less baskets. 4/5 (four-fifths) is equal to 80%.
