the time of Florence Nightingale? From the census of 1851, we have the following information. 20-29 24.5 50-59 54.5 60-69 64.5 30-39 40-49 Age range (yr) Midpoint x Percent of 70-79 80+ 34.5 44.5 74.5 84.5 nurses 5.7% 9.7% 19.5% 29.2% 25.0% 9.1% 1.8% (a) Using the age midpoints x and the percent of nurses, do we have a valid probability distribution? Explain. (b) Create a bar graph for the probability distribution of part (a). (c) Find the probability that a British nurses selected at random in 1851 was 60 years of age or older. (d) Compute the expected age u of a British nurses contemporary to Florence Nightingale. (e) Comnute the etandard deviation s for ages of nursee ehown in the distribution
