b. how is the sample size impacted if we change our confidence level to 90%?
c. how is the sample size impacted if we change the error requirement to no more than two ounces per cooking team?

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.
