Answer:
Null hypothesis
Alternative hypothesis
t = - 2.05
Degree of freedom df = 14
P-value = 0.0298
Decision rule: To reject if significance level ∝ is greater than P-value.
Conclusion: We reject at the level of significance ∝ = 0.1, thus there is sufficient evidence to conclude that the machine is underfilling the bags.
Step-by-step explanation:
Given that:
Population mean = 443
Sample size n = 15
Sample mean = 434
standard deviation = 17
Level of significance ∝ = 0.01
The null and the alternative hypothesis can be computed as:
Null hypothesis
Alternative hypothesis
The t-test statistics can be computed as :
t = - 2.05
Degree of freedom df = n - 1
Degree of freedom df = 15 - 1
Degree of freedom df = 14
From t distribution table; from the area in the lower tail to the left of t = -2.05 and for the degree of freedom df = 14, it is given by 0.0298
Thus, P-value = 0.0298
Decision rule: To reject if significance level ∝ is greater than P-value.
Conclusion: We reject at the level of significance ∝ = 0.1, thus there is sufficient evidence to conclude that the machine is underfilling the bags.

Answer:
The answer is 1/4
Step-by-step explanation:
move all terms with variables to one side and you get this : 20n=5
divide the variable side by 20 so you are left with the variable by itself. then do the same to the other side. 5/20 is 1/4
Answer:
-1
Step-by-step explanation:
To find the slope given two points use the formula
m = ( y2-y1)/(x2-x1)
= ( 8-2)/(4-10)
= 6/-6
= -1
I believe the answer is (4,3). Hope that helps.
