It must be negative
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,
$72
Since 20% of 60 is 12 (do .2 * 60) you add $12, which is the answer to the multiplication, to the original.
26.= 6000ft.
1.convert the yards to feet 100 yards= 300 ft
2. to find the area multiply the 20 ft by 300 ft
3. answer is 6000 ft
4 . if the answer needs to be in yards use a converter to convert the feet to yards
