Use the 68-95-99.7 Rule to approximate the probability rather than using technology to find the values more precisely. The daily closing price of a stock (in $) is well modeled by a Normal model with mean $159.91 and standard deviation $3.91. According to this model, what cutoff value(s) of price would separate the following percentage? a) lowest 2.5% b) highest 50% c) middle 68% a) The cutoff value would be $ (Type an integer or a decimal rounded to the nearest cent as needed.) b) The cutoff value would be $ (Type an integer or a decimal rounded to the nearest cent as needed.) c) The lower cutoff value would be $ (Type an integer or a decimal rounded to the nearest cent as needed.) The upper cutoff value would be $ (Type an integer or a decimal rounded to the nearest cent as needed.) d) The cutoff value would be $ (Type an integer or a decimal rounded to the nearest cent as needed.) d) highest 16% Use the 68-95-99.7 Rule to approximate the probability rather than using technology to find the values more precisely.
