Answer:
a) Any sample statistic used to approximate a population parameter.
Step-by-step explanation:
An unbiased estimator is any sample statistic used to approximate a population parameter.
In mathematics, the bias of an estimator refers to the difference between the true value of the parameter being estimated and the estimator’s expected value.
If a statistic is not an underestimate or overestimate of the population parameter, then it is unbiased.
That is why an unbiased estimator is an accurate sample statistic used to approximate a population parameter.
Answer:
add all of the sides
Step-by-step explanation:
1/3a - 5 - (1/6a + 3)
= 1/3a - 5 - 1/6a - 3
= 1/6a - 8 Answer
We’re given two numbers - 1.46 and 0.751 - and since we know that they were both collected last week (although from two separate barrels), we want to add these two numbers up. Aligning the numbers up ( for example, the 1 in 1.46 should align with the 0 in 0.751 because they’re both in the ones place, or the place before the decimal), we get
1.46
+0.751
————
-.—1
To fill in the blanks, we want to start by adding the 6 and 5, which is 11. Since the first digit of 11 is 1, we can carry the 1 into the space to the left to get
1
1.46
+ 0.751
————-
-.-11
For the next digit, we have 4+7=11, but we add the one on the top to get 12. 12-10=2, so we have
1
1.46
+ 0.751
————-
-.211
Since 1+1+0=2, we have 2.211 as our answer.
