How do you find the population mean for a 95 percent confidence interval?
It depends whether or not the observations are independent and on the distribution of the variable that is being measured or the sample size. You cannot simply assume that the observations are independent and that the distribution is Gaussian (Normal).
How is frequency distribution useful to us?
I suspect you are referring to a sample frequency distribution.Providing that the sample size is sufficiently large there are various kinds of information that can be gleaned from one:the approximate range of values in the populationthe location of the population as measured by the value that appears most often in the frequency distribution-known as its modethe likely shape of the population's distribution, in particular whether it is symmetric or skewedobviously how values of the population variable are distributedwhether there are any curious peaks or valleys, even when the sample size is largethe amount of variation around the central value
When calculating the mean the researcher should use data measured at which level?
interval
True or false the amount of alcohol consumed by a person per week will be measured on an interval scale?
true
The Pearson product-moment correlation coefficient r requires that variables are measured with?
Either an Interval or an Ordinal Scale
What is the frequency of a wave measured by?
The frequency of a wave is measured in Hertz.

What unit is sound frequency measured in?
Frequency is measured in hertz. Cycles per second.
Why are mean and mode are inappropriate to describe a data with pounds?
They can be appropriate. The answer has nothing whatsoever to do with the units of measurement: the appropriateness depends on the distribution of the variable that is being measured.
What is frequency of wave measured in?
It is measured in Hertz (Hz).
What is measured on hertz?
Frequency
What are the variables on a sound spectrogram and how are they measured?
A sound spectrogram measures the frequency and wavelengths of sound waves. The frequency is measured in Hertz and the wavelengths are measured in meters.
Indicate the frequency level of a sound?
Frequency is usually not measured in "levels" (though the sound pressure or volume is) Frequency is measured in Hz (Hertz) or vibrations per second. Sound pressure is measured in Decibels
Can a variable measured at the interval or ratio level can have more than one arithmetic mean?
A variable measured at the interval or ratio level can have more than one arithmetic mean.
What it means for a wave to have a frequency of hertz?
hertz is what frequency waves are measured in.
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
What is frequency physics?
The Study of Frequency Waves. Types, how they are measured, etc...?
