Answer:
And rounded up we have that n=1068
Step-by-step explanation:
We have the following info given:
the confidence level desired
represent the margin of error desired
The margin of error for the proportion interval is given by this formula:
(a)
The confidence level is 95% or 0.95, the significance is 
and the critical value for this case using the normal standard distribution would be 
Since we don't have prior information we can use 
as an unbiased estimator
Also we know that 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Answer:
division equation
x/6 = 12
The size he should buy = 72 ounces
Step-by-step explanation:
Mr Ortega bought a ham. He wants to divide it into 6 ounce serving for 12 people . The division equation to find what size of ham Mr Ortega should buy is represented below.
Mr Ortega wants to share for each person 6 ounce serving for 12 people.
Let the amount of ounce he will buy = x ounces
Therefore, the division equation to find what size of hams Mr Ortega should buy will be
x/6 = 12
To find x we cross multiply
x = 12 × 6
x = 72 ounces
