A random sample of 50 adult males in Toronto,Ontario were randomly selected and their weight,in kilograms,was recorded to the nearest kilogram.In order to compute a bootstrap confidence interval for the median,200 subsequent bootstrap samples were taken and the resulting sample medians were ordered from lowest to highest.The first 10 and last 10 ordered medians are given below: First 10: 68.0,68.5,69.0,69.0,69.5,70.0,70.0,70.0,70.5,70.5
Last 10: 93.5,94.0,94.0,94.5,94.5,95.0,95.0,95.5,95.5,96.0
Use the percentile method to compute a 95% bootstrap confidence interval for the true median weight of adult males in Toronto,Ontario.
A) (70.0,95.5)
B) (69.5,95.0)
C) (70.0,94.5)
