Answer:
There is sufficient statistical evidence to suggest that the average weight of the ground beef packaged in small trays is 1 pound
Step-by-step explanation:
Here we have to perform a t-test
Mean = Sample mean = 1.04 lb
μ = Population mean = 1 lb
s = Standard deviation of 0.19
n = Sample size = 45
Null hypothesis H₀ = 1
Alternative hypothesis Hₐ > 1
Therefore from
we have
t = 1.412
Critical t at 5% confidence level = 1.68
at 5 % confidence level we obtain the probability P is;
P = 0.0825 > 0.05 Therefore we accept our null hypothesis that the average weight of ground beef per pack is 1 pound.

Answer:C
Step-by-step explanation:In a box plot the median is the line that lines with the number that on the box plot. So the line is between 8 and 9 but to find the number that is between 8 and 9,first add 9+8=17 then divide 17 with 2 which is 17÷2=8.5.Therfore the numbers that are between 8 and 9 is 8.5.
I think it is 7/12 because if you subtract the two numbers, you get 7/12
√(4×18)= √72 or √36√2= 6√2 simplified
