Answer:
We can reject the hypothesis at the 0.05 significance level.
Step-by-step explanation:
given that an urn contains a very large number of marbles of four different colors: red, orange, yellow, and green. A sample of 12 marbles drawn at random from the urn revealed 2 red, 5 orange, 4 yellow, and 1 green marble.
H0: All colours are equally likely
Ha: atleast two colours are not equally likely
(Two tailed chi square test at 5% significance level)
color Red Orange Yellow Green total
Observed O 2 5 4 1 12
Expected E 3 3 3 3 12
(O-E)^2/E 0.3333 5.3333 0.3333 5.3333 11.3333
chi square = 11.3333
df =3
p value = 0.010055
Since p < 0.05 we reject H0
We can reject the hypothesis at the 0.05 significance level.
This looks hard... good luck ! :D
Answer:
It is "A" or in other words the one that says (x-5)2+3 because when you graph it you can see it is the only one touching that point!
Step-by-step explanation:
Let's say that ST is side b
<span><span>Use the Law of Sines to find side b.</span><span>
b / sin(B) = a / sin(A)</span><span>
b / sin(59°) = 7 / sin(79°)</span><span>
b = (sin(59°) x 7) / sin(79°)</span><span>
b = 6.112
That is answer B.) 6.1 yards
Hope this helps!</span></span>
