Suppose data on the price per gram of saffron is collected. A histogram of the prices shows that the distribution is roughly symmetric and unimodal. The mean price per gram of saffron is $11.48 and the standard deviation is $2.12. A local grocer, Food And Stuff, is selling saffron for $8.99 per gram. What is this price in standard units? Round to the nearest hundredth. Would this price be considered unusual or not? O Cannot be determined from the information given O z = 1.17; This price is not unusually high. O z = -1.17; This price is not unusually low. O z = 1.17; This is unusually expensive saffron. O z = -1.17; This is unusually inexpensive saffron
