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.
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 is Confidence Intervals of Interval Estimate?
An open interval centered about the point estimate, .
A sample average can be used to estimate a population average precision if the sample is?
large
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
What does your grade point average have to be to get into Texas tech?
Same as Blutarsky...zero point zero.
How does the slope differ from average rate of change?
They are the same for a straight line but for any curve, the slope will change from point to point whereas the average rate of change (between two points) will remain the same.
If Tina swims 4 miles upstream at 1 mph and back downstream to the same point to the same point at 4 mph what is her average speed?
8 MPH
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.
What is used to estimate the population parameter?
point estimate
Is the sample mean a point estimate of the population mean?

Is estimate and guess the same?
Yes estimate and guess our the same.
What average do you need to be accepted into university?
Each university has its own admission requirements. They do not all require the same grade point average, and they also consider elements other than grade point average when deciding whether to accept a particular applicant.
What can you say about the average velocity?
I could say it's the same as the distance covered divided by the time to cover it, in the direction from the starting point to the end point.
What is Hypothesis Testing of Point Estimate?
A statistical estimate of the population parameter.
How do you estimate the average of a number?
The average of a single number is itself.
What is GPA test?
It is a test where you find out your GPA (Grade Point Average)
