To calculate the standard error for a proportion, you can use the formula: [ SE = \sqrt{\frac{p(1 - p)}{n}} ] where (p) is the sample proportion and (n) is the sample size. If the proportion is not given in your question, you'll need to specify a value for (p) to compute the standard error. For a sample size of 25, substitute that value into the formula along with the specific proportion to find the standard error.

To find the volume of a sample of gold, you can use the formula: volume = mass / density. Gold has a density of approximately 19.32 grams per cubic centimeter (g/cm³). Therefore, if you have a mass of ( m ) grams, the volume (V) can be calculated as ( V = m / 19.32 ) cm³. Substitute the mass value into this formula to obtain the volume.

Take the old value and subtract from the new value, then divide by the old value. Multiply by 100. That number representsthe percent change.

In a range of cells it can find the highest value. So if you had numbers in all the cells from A2 to A20 and wanted to find the highest you could use the following formula: =MAX(A2:A20)
I find the following source useful for sample letters. A sample apology letter is also included. See if it helps.

The empirical formula of the oxide of Bromine would be Br2O5. We can determine this by assuming a 100 g sample, which would contain 71.4 g of Bromine and 28.6 g of Oxygen. Then we convert these masses into moles and divide by the smaller value to find the mole ratio, which gives the empirical formula.
In general when you take a sample of values of a random variable you will find that those values lie around some central value that is characteristic of the total population for the random variable. A measure of central tendancy (such as a sample mean, sample mode or sample median) is a statistic which is intended to estimate the central value of the population using the values in the sample in some way.
