Task 1 . The income (in thousand $) of 5 small companies labeled AA , BB , CC , DD , EE has been calculated and the results are as follo,;vs: 2.49j 2.39j 2.39, 1.79, 3.8 .
1. Put the obtained data as points on the following coordinate system.

Income value

AA BB CC DD EE Company

2. Calculate the mean value from the sample for these data:

On the chart draw a line y = x (a horizontal line at the level of the mean of the sample) and for every measurement mark the difference between the value of the measurement and the sample mean.
3. Calculate the samples variance, standard deviation and the estimator of variance:

Icr2 =_.!_ f=_(xi -

I• I

__ n i=l

x_) _= iT

4. Write proper values into the following tagged fields and interpret the results obtained:

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

infinity is the answer
