Z = 4 , w = 6
z = x , w = 8
Therefore, z = (4*8) / 6
= 32 / 6
= 16/3 = 5.333
Answer:
Step-by-step explanation:
A type 1 error is committed when a true null hypothesis is rejected. Looking at the given scenario, given that the null hypothesis, H0 states is stated as follows:
The mean age of the horses on a ranch is 6 years, then a type 1 error would be made if the conclusion states that the mean age of the horses on a ranch is lesser or greater than 6 years when it is actually 6 years. Therefore, the correct option is
You cannot conclude that the mean age of the horses on a ranch is 6 years when, in fact, it is.
4/32 = x/100
answer: x = 12.5
Answer:
r = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)
m = 
, that is
= ( cross- multiply )
7(r + 3) = 7 ( divide both sides by 7 )
r + 3 = 1 ( subtract 3 from both sides )
r = - 2
