Question 1174028
<pre><font face = "Tohoma" size = 3 color = "indigo"><b>
Hi,
... such that at least 90% of the cartons have more that 16 ounces of ice cream. 
What should be the mean amount of ice cream put into these cartons by this machine?

Normal Distribution: σ = .18

{{{z =blue (x - mu)/blue(sigma)}}}  

{{{ (-z)( .18) + 16 =  mu }}}              using z = -1.282,  gives upper 10%


(1.282)(.18) + 16 = μ = 16.23 (rounded to same decimal points as  σ )


Wish You the Best in your Studies.
