Question

What was the age distribution of nurses in Great Britain at the time of Florence Nightingale? We have the following data from Florence Nightingale’s writing

Age Range (yr)	20-29	30-39	40-49	50-59	60-69	70-79	80+
Midpoint x	24.5	34.5	44.5	54.5	64.5	74.5	84.5
Percantage of Nurses	5.7%	9.7%	19.5%	29.2%	25.0%	9.1%	1.8%

Using the age midpoints x and the percentage of nurses, do we have a valid probability distribution? Explain
Use a histogram to graph the probability distribution of part (a).
Compute the expected age (mean) of a nurse.
Compute the standard deviation for ages of nurses.
What is the probability that a British nurse selected at random was younger than 60?
