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 S) 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% d) highest 16% a) The cutoff value would be $ 153 18 (Type an integer or a decimal rounded to the nearest cent as needed) b) The cutoff value would be $ 159 91 (Type an integer or a decimal rounded to the nearest cent as needed) c) The lower cutoff value would be $ 156 00 (Type an integer or a decimal rounded to the nearest cent as needed.) The upper cutoff value would be $ 163 82 (Type an integer or a decimal rounded to the nearest cent as needed) d) The cutoff value would be $ 162.07 (Type an integer or a decimal rounded to the nearest cent as needed)
