The sample mean is an unbiased estimate of the population
mean. This tells us that the mean of all sample means is equal to the
population mean. Since we know that the population mean is 5.67, we also know
that the mean of sample means is also 5.67.
The answer is -76. Do 82-6 which is 76. Then just add a negative sign.
30 is the range, you take the maximum and subtract the minimum
That would be the first and the last functions.
The answer is 4x2-5x;Area= 114 in<span>2 i think</span>
