Answer:
The sample proportion 
is within 0.03 of the true proportion of customers who are under age 21 is 0.803
Step-by-step explanation:
Total no. of customers = n = 400
We are given that the true population proportion of customers under age 21 is 0.68.
So, p =0.68
q=1-p=1-0.68=0.32
Standard deviation =
We are supposed to find the probability that the sample proportion is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that is between 0.68 - 0.03 and 0.68+ 0.03
Using Z table
Hence the sample proportion is within 0.03 of the true proportion of customers who are under age 21 is 0.803
The equation would be:
200+200x=b
x is equal to hours, while b is equal to bacteria.
Every day has 24 hours.
24*5= 120
Plug it in.
200+200(120)=
24200= 5 days of bacteria
I hope this helped you!

Answer:
1,196
Step-by-step explanation:
Divide 8,367 by 7 and that will come out to 1195 with two tables left over. You will need to use a extra box and add packing paper to put the 2 extra tables. then if you add 1,195 + 1= 1,196
