Answer:
the answer is in the explanation
Step-by-step explanation:
we are given
sample size
= 10 for each formulation
mean
(formulation 1) = 121
mean
(formulation 2) = 112
s (standard deviation ) = 8 mins for each case
null hypothesis
μ2 = μ1 (both have average same time)
alternative hypothesis
μ2 < μ1
under
the test statistics is

t = -2.5
ItI = 2.5
The P-value at ItI = 2.5 at
= 0.05 μ = 0.010699
check the remaining solution and diagram in the attached image
You would put these in a fraction then cross multiply so 15/1800 and 3/x then you get 5400 equals 15x then divide by 15 on both sides to get x equals 360
Answer: The solution would be any value that is -2 and lower.
Step-by-step explanation:
Okay, so our equation is c ≤ -2, so any value that is -2 and below would be correct for this inequality.
The answer is 20. You use 20 markers for it all.
