With some manipulation, the rydberg equation can be rewritten in the form e=constant×(1nf2−1ni2) which allows you to calculate the energy of the emitted light. what is the value of the constant needed to complete this equation? express the constant in joules to three significant figures.

The Mean and standard deviation of random variable is Respectively.

The given problem describes a binomial distribution with

trials, i.e,

a)The mean is given by;

The standard deviation is given by the formula,

b)The mean means that in an experiment of adult smokers, of adult smokers started smoking before turning years old so on an average smokers who started smoking before turning years.

c)It would be unusual to observe smokers who started smoking before turning years old in a random sample of adult smokers because is far greater than the mean of the distribution.   is greater than the standard deviations from the mean of the distribution.
