A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
What is the best estimate for 1235 and1045 and 975?
To the nearest ten, 1240, 1050 and 980 respectively.
How do you calculate percentage error?
It is your estimate minus the true value divided by the true value and multiplied by 100. So, % error = (estimate - actual) / actual * 100, in absolute value. For example, if you estimate that there are 90 jelly beans in a jar when there are actually 130 your percentage error is: (90-130)/130 * 100 = -40/130 * 100 = -0.308*100 = -30.8% After absolute value, the answer is simply 30.769, or 30.8%.
If a given input value yields four output values that relationship can be best described as a relation true or false?
This is true. If a given input value yields four output values that relationship can be best described as a relation.
What does estimated mean in math?
To make an educated guess. for instances if you were asked to estimate half of 1426, you would round down to to 1400, and half that which is much easier. Half of that that is 700, therefore you would estimate the answer to be around 700.
