Answer:
435 cupcakes baked in one week if that’s what your asking.
If you divide 311 by 500 you would get 0.622 as your decimal
Each of these questions is substantially the same as the others. The answer is, "it depends" on what you want a random sample of. If you want random people in the country, you will not get that from these protocols.
If you want random people that meet certain criteria (have phones, shop in eyeglasses stores, use specific venues), then these protocols will deliver.
-8 and 16 is the answer individually but if you add them the answer is 8
Answer:
C.I = 0.108 ± 0.022
Step-by-step explanation:
In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.
Therefore, the sample proportion will be:


= 0.108
p' = 0.108
To find the margin of error, we have:
M.E = ½ * length of confidence interval
Where length of confidence interval = 0.130 - 0.086
= 0.044
Therefore,

Margin of error = 0.022
The confidence interval is expressed as:
p' ± M.E
= 0.108 ± 0.022
