Cereals sodium values have a mean of 167 and a standard deviation of 77.3. Find the z-score for the cereal that has a sodium value of 0. How would you interpret this z-score?

Normal Distribution The following table shows the temperature at noon on February 21, 2018 in 5 different Canadian cities. Calculate the z-score for each temperature measurement, and find which city was experiencing the most "exceptional" (out-of-ordinary) temperature on that day. City Temp. on February 21 Average Temp. in February Std. Deviation z-score Montreal 3.4 -7.7 2.7   Toronto 3.2 -4.5 2.3   Vancouver -3.3 4.9 1.5   Regina -27 -11.7 4.2   Halifax 5.4 -5.2 2   The city with the most "exceptional" (out-of-ordinary) temperature on that day is choose: -Montreal -Toronto -Vancouver -Regina -Halifax
