A credit score measures a person's creditworthiness. Assume the
average credit score for Americans is 709. Assume the scores are
normally distributed with a standard deviation of 53. a) Determine
the interval of credit scores that are one standard deviation
around the mean. b) Determine the interval of credit scores that
are two standard deviations around the mean. c) Determine the
interval of credit scores that are three standard deviations around
the mean. a)The interval of credit scores that are one standard
deviation around the mean ranges from nothing to nothing. (Type
integers or decimals. Use ascending order.) b)The interval of
credit scores that are two standard deviations around the mean
ranges from nothing to nothing. (Type integers or decimals. Use
ascending order.) c)The interval of credit scores that are three
standard deviations around the mean ranges from nothing to nothing.
(Type integers or decimals. Use ascending order.)
