Answer:
c) Sample parameters are usedto make inferences about population statistics
Step-by-step explanation:
In statistics we use samples to make inferences about population
That is the great advantage of the whole role of distribution. Once you know a particular situation or experiment, that you can associate to one specific distribution and compute parameters, you can obtain from a relative smaller quantity of dataand with good approximation, inferences about the whole population (that can be conform by a very big numbers of elements)
This equals to -55999.49499
Breaking down the value 12.45
12.45 = 10 + 2 + 0.4 + 0.05
The value of digit '4' in 12.45 is 0.4
1/10 of 0.4 is 0.4 ÷ 10 = 0.04
One possibility of Landon's time = 12.54 [Need to make sure that Landon takes longer than Ervin since he comes second]
