What are the problems of missing frequencies in a frequency table in statistics?

Conclusions based on missing frequencies are likely to be seriously flawed. However, if the data follow a known distribution, it may be possible to get some indication of the likely values for the missing frequencies. Nevertheless, this would weaken any conclusions.

How do you find mean of 50 observations for the data is 3.72 the 2 frequencies are missing in the frequency table?
A=14,b=8
How do you find the missing relative frequency?
The answer depends on what information you do have.

What wavelenghts are used to study star's?
To make a long story short, all of them. Various properties of starts can be studied by measuring the frequencies and corresponding intensities of electromagnetic radiation from a star. Assuming a star is not moving with respect to the Earth (or, put more simply, is moving as fast as the Earth is and in the same direction), the intensities of the wavelengths emitted by the star can be seen from Earth as having a bell curve distribution whose peak corresponds with the star's temperature. However, this bell curve distribution is not perfect. At several specific frequencies, the intensity of emitted light is greatly decreased. The frequencies influenced by this effect and the degree that this effect occurs are dependent on the component elements and corresponding concentrations of these elements. Therefore, by analyzing the frequencies that are "missing" from the electromagnetic spectrum, one can derive the chemical composition of the star. If the star is moving with respect to the Earth, this distribution of light is distorted even more. As a consequence of relativistic physics, the wavelengths of light emitted from the star will appear to have a higher frequency as seen from the Earth than what was emitted if the star is moving toward the Earth (this is called "blue shift", as visible colors appear more blue). Conversely, the Earth will see lower frequencies of light than were originally emitted if the star is moving away from the Earth (this is called "red shift", as visible colors appear more red). However, since the distribution of light emitted from the star has "missing" frequencies, and since the original emitted frequencies are known for these "missing" frequencies (as they correspond with the frequencies emitted by known compounds), the entire distribution of light can be shifted back to its rightful place. Moreover, the amount of this shift is dependent of the relative speed between the Earth and the star; therefore, the star's speed can be determined from the star's light as well.
How many of the missing kids are found alive?
There are not reliable statistics available because of the various reporting methods, the number of agencies involved at state and/or federal level and so forth Minors who are unaccounted for are grouped into many categories such as , endangered missing, endangered runaways, family abductions, lost, missing or injured children, non family abduction, stranger abduction, etc. Needless to say the statistics for missing children are very troubling and very inaccurate both on the plus and minus side.
