Using it's concept, it is found that the sample mean of cars sold per week is of 4.96.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the sum of the 26 observations is given by:
S = 1 + 1 + 4 + 2 + 4 + 10 + 8 + 5 + 9 + 6 + 1 + 5 + 6 + 5 + 7 + 1 + 4 + 6 + 8 + 9 + 2 + 5 + 9 + 5 + 3 + 3 = 129.
Hence the mean is given by:
M = 129/26 = 4.96.

The answer is ...
150 this is how you find it
Ok so you 10,000 cars you divide that by 200
That is going to give you 50 groups of 200 and if each 200 cars have 3 cars with a defect you just do 50•3
Which is how you get 150 cats

Answer:
One part of the evidence that the color of the flame created is from the metal ion and not from the chemical is that not any of the flames with dissimilar metals had a similar color (for each metal had its flame color). Even if most of the metals tested had chloride, the colors of the flames were all dissimilar. The two flames that both had copper (one had copper (II) chloride and the other had copper (II) sulfate) were exactly close in color. The one was green-blue, and the other was a bright green. This displays that they were nearly the same, and the minor difference could be credited to error.
