Answer:
8 pizzas should be ordered.
Step-by-step explanation:
To get the number of pizzas to be ordered, all we simple need to do is to multiply the numbers of the group members by the amount to be consume by each group member. That is;
Number of pizzas to be ordered = amount to be consume by each group member × number of group members.
amount to be consume by each group member =
Number of group members = 24
We can now proceed to insert our values into the formula
Number of pizzas to be ordered = amount to be consume by each group member × number of group members.
Number of pizzas to be ordered = × 24
=
= 8
Number of pizzas to be ordered = 8
Therefore, 8 pizzas should be ordered.

Answer:
So the answer for this case would be n=22547 rounded up to the nearest integer
Step-by-step explanation:
Let's define some notation
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
represent the margin of error desire
The margin of error is given by this formula:
(a)
And on this case we have that ME =+1 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance would be and the critical value
, replacing into formula (b) we got:
So the answer for this case would be n=22547 rounded up to the nearest integer
