Answer: We accept H₀
There is not convincing evidence that the mean contents of cola is less thanthe advertised
Step-by-step explanation:
Our case normal distribution, with σ = 3
The sample is of 6 then n = 6
The calculated mean from given data is : 299.03
sgnificanc level: α = 0.05
Then H₀ null hypothesis μ₀ = 300
the alternative hypothesis μₐ < 300
As n < 30 we have to go to t table we look fr α = 0.05 and gl = 5
we find t(c) = 2.015
Now we calculate t (s) = ( x - μ₀ )/( σ/√n ) t(e) = -0.97/1.224
t(s) = - 0.79
The test is one tail test ( to the left) and t(s) = -0,79 is bigger than
t (c) = -1.64
So we are in the acceptance zone. We accept H₀
