Step-by-step explanation:
I am still in 7th grade, I haven't learned this yet. I need the points
True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
Answer: The answer is square root of -2 Hope this help :)
Step-by-step explanation: square root of -80 so what number can equal to 80 well 10*8 so it will be sqaure root of -8 ,but that is not answer so you have to simplify -8 so 4*2 equal to 8 so the answer will be sqaure root of -2
