A food safety engineer has discovered that a food warmer has temperature problems. While they set up the temperature at 78c, it heats with the mean of 78c but a standard deviation of 2c. The problem is that any food that drops below 74c can create food poison for the consumers. What is the probability of having non-standard food from this food warmer? In other words, what proportion of food can be a health hazard? (Use the number only without any extra character or % sign)
Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has noeffect, so the probability of a girl is 0.5. Assume that the groups consist of 32 couples. Complete parts (a) through (c) below. Find the mean and the standard deviation for the numbers of girls in groups of 32 births.
An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with a mean of 119 cm and a standard deviation of 5.7 cm. A. Find the probability that one selected subcomponent is longer than 121 cm. Probability = B. Find the probability that if 4 subcomponents are randomly selected, their mean length exceeds 121 cm. Probability = C. Find the probability that if 4 are randomly selected, all 4 have lengths that exceed 121 cm. Probability =
