How do you find the raw score when you don't have the z score?
Go back to the basic data, estimate the sample mean and the standard error and use these to estimate the Z-score.
What do you need to estimate?
to round the numerals you are use to estimate
When is using the mean as a measure of central tendency useful?
When your data is symmetric and narrowly spread about it.Each measure of central tendency has strengths and weaknesses. The mean takes every piece of numeric data and treats them all as equally weighted. Outliers will have equal weight with any other measure. In the long run, when you want to estimate a value that is least different from all values, use the mean. If you want your estimate to be closest to absolutely correct or to be absolutely correct most often, use the mode, and if you want your estimate to be as likely to be above the true value as below, use the median.
A sample mean is the best point estimate of the?
he population mean
How do you use comparable numbers to estimate multiplication?
the answer is yes because you can estimate any numbers
How do you find the raw score when you don't have the z score?
Go back to the basic data, estimate the sample mean and the standard error and use these to estimate the Z-score.
A sample of 16 people reveals the mean yealy to be 60 pound and stand deviation of 20 pound What is the value of the population mean?
You use the sample mean as the estimate of the population mean; then as standard practice place confidence limits on the mean; most use 95%.
When you use estimate?
You can estimate when an exact answer is not needed.
What is the mathematical term for estimate?
Mathematicians use the word estimate.
What does OOM estimate mean?
OOM (Order of magnitude) estimate
What does an eyeball estimate mean in construction work?
A rough estimate
Is the sample mean a point estimate of the population mean?
A point estimate of a population parameter is a single value of a statistic. For example, the sample mean x is a point estimate of the population mean μ. Similarly, the sample proportion p is a point estimate of the population proportion P.
What do you need to estimate?
to round the numerals you are use to estimate
How can you estimate a cat's length if you did not have ruler?
To estimate the length of a cat's body without the use of a ruler to measure, use an object that an estimate measurement is known to estimate the length of the cat.

True or false the sample mean is a point of estimate of the population mean?
Nearly true. It is a point estimate, not point ofestimate.
TO ESTIMATE THE AVERAGE AGE OF STUDENTS A SAMPLE OF 50 PARTICIPANTS WAS OBTAINED, WITH A MEAN OF 16 AND A POPULATIONAL VARIATION OF 9, calculate:* POINT ESTIMATE OF THE MEANS* 95% AND 99% CONFIDENCE INTERVAL ESTIMATES FOR THE MEANS?
Point Estimate of the Mean: The point estimate of the mean is 16, since this is the sample mean. 95% Confidence Interval Estimate for the Mean: The 95% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 1.96*(9/sqrt(50))) = 16 +/- 1.51 = 14.49 to 17.51 99% Confidence Interval Estimate for the Mean: The 99% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 2.58*(9/sqrt(50))) = 16 +/- 2.13 = 13.87 to 18.13
