What is the energy of a photon that has the same wavelength as a 12-eV electron? (h = 6.63 x 10-34 J*s)
Standard Error
An estimate of the variability or precision of a sample mean (or other estimate) as an estimate of the population mean.
Random Sample
A sample drawn in such a way that each member of the population has an equal chance of being selected, ensuring that the sample represents the population as a whole.
Large Animals
Refers to animals of considerable size, often categorized based on weight and height, commonly including species such as elephants, giraffes, and whales.
Margin of Error
Margin of error is a statistic expressing the amount of random sampling error in a survey's results, indicating a confidence interval within which the true population parameter is likely to lie.
