Answer:
a) 0.373 probability that a randomly selected carton has a weight greater than 8.13 ounces
b) 0.097 probability that mean weight of 16 randomly selected carton is greater than 8.13 ounces
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8 ounces
Standard Deviation, σ = 0.4 ounce
We are given that the distribution of weights of ice cream cartons is a bell shaped distribution that is a normal distribution.
Formula:
a) P(weight greater than 8.13 ounces)
P(x > 8.13)
Calculation the value from standard normal z table, we have,
b) P(weight of 16 randomly selected cartons is greater than 8.13 ounces)
P(x > 8.13)
Calculation the value from standard normal z table, we have,
