Temperature danger zone is defined as the specified range of temperature at which micro organisms grow rapidly in food. The danger zone ranges from 40F to 140F. To keep food out of danger zone, cold food must be kept at or below 40F while hot food must be kept at or above 140F. From the question given above, three of the food fall in the temperature danger zone, but cottage cheese is still safe at 40F because of the fermentation process by which it was made and shell egg is still safe at 43F because it has shell to protect it. Thus, the correct answer is POTATO SALAD AT 46F.
In this problem we are given the mean of $1100, SD of $150 and x equal to $900. In this case, we need to use the z-score table to answer the problem:
z = (x-mean)/sd
z = (900-1100)/150
z = -1.33
from z-table, the probability at the left of z= -1.33 is equal to 9.18%
