( a ) The null hypothesis, represented by 
, should be equivalent to 0.6 pounds per square inch, considering it normally is predicted to be equivalent to the population parameter, which, in this case, is 0.6 psi ( pounds per square inch. ) The alternative hypothesis on the other hand contradicts the null hypothesis, and as the manager feels the pressure has been reduced, the alternative hypothesis points that the pressure is less than 0.6 psi -
<em>stigma is represented by the sign ( σ )</em>
( b ) Now if you were to reject the null hypothesis when true, that would lead to a type I error. That would mean that to reject the fact that σ = 0.7, and accept that σ < 0.7, even though σ = 0.7 is true, would make a type I error.
_______
( c ) A type II error is quite the opposite. Accepting the null hypothesis while rejecting the alternative hypothesis would make a type II error.
An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.
Answer:
y = 4x + 13
Step-by-step explanation:
m = 4 at point (-3,1)
y = 4x + b
1 = 4(-3) + b
1 = - 12 + b
b= 13
y = 4x + 13
Answer:
70 weeks
Step-by-step explanation:
500g = .5kg
140 - .5w = 105
35 = .5w
70 = w
Answer:
5
Step-by-step explanation:
To find the area of a triangle we have to multiply base times height divided by 2. 4 x 5 = 20 divided by 2 = 10. So x=5 Hope this helps and have a great day!
