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.
