To predict the number of females in the school, we can use the proportion of females from the sample. In the sample, 30 out of 75 students are female, which is 40%. Applying this percentage to the total student population of 1000, we estimate that there are approximately 400 females in the school (0.40 * 1000 = 400).
It is the sample mean age of 21.7.
You calculate the actual sample mean, and from that number, you then estimate the probable mean (or the range) of the population from which that sample was drawn.
To compute the point estimate of a population mean, you take the sample mean. This is done by calculating the average of the data values in the sample. The sample mean is then used as an estimate of the population mean.
Yes, I can provide sample letters of recommendation for high school students.
The symbol for sample mean is typically represented by ( \bar{x} ) (pronounced "x-bar"). It is calculated by summing all the observations in a sample and dividing by the number of observations. This statistic provides an estimate of the population mean based on the sample data.
Parameter is any attribute Statistic are the measured values of a parameter. A statistic is a sample value such as the average height of a group of students. A parameter is a functional constant such as the mean of a normal distribution. Statistics are often used to estimate parameters. For instance, a sample average is an estimate of the mean.

Not a lot. After all, the sample sd is an estimate for the population sd.

A point estimate is a single value used to estimate a population parameter, such as the sample mean used to estimate the population mean. Confidence intervals can also be used to provide a range within which the population parameter is likely to lie.
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.
