Answer:
Step-by-step explanation:
given that
A cereal manufacturer is concerned that the boxes of cereal not be under filled or overfilled.
Each box of cereal is supposed to contain 13 ounces of cereal.
A random sample of 31 boxes is tested.
The average weight is 12.58 ounces and the standard deviation is 0.25 ounces.
Sample mean = 12.58
Sample std deviation = 0.25
Sample size = 31
Sample std error = 
confidence interval can be calculated using t critical value because population sd is not known.
df = 30
t critical for two tailed = 1.697
Margin of error = 
conidence interval = 
Since this does not contain 13 oz. we reject the claim that each box contains exactly 13 oz.
Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do
25.12*3
75.36
then you add the 64 from the square to get your answer
75.36+64
139.36
