Answer:
E. Assuming that the mean amount of grass eaten by cows is equal to the mean amount of grass eaten by horses, the probability of observing a test statistic of at least 1.664 is 0.0487
Step-by-step explanation:
Given that :
Test statistic, t = 1.064
P-value = 0.0487
Hypothesis : To test if grazing cows eat more grass than grazing horses
The null hypothesis will be :
H0 : μ1=μ2 (that is there is no difference on the mean number of grass eaten by cows and horses).
Alternative hypothesis ; H1 : μ1 > μ2
The null is assumed true unless tested otherwise, the P-value is used as a probability metric for the rejection or acceptance of the null.
Therefore, if the null is True in this scenario, then, the probability of observing a test statistic of at least 1.664 is 0.0487
There are 95 yellow beads and 95/250 is 0.38 which is equal to 38%
Answer:
The height is 15 m.
Step-by-step explanation:
V = (pi)r^2h
375(pi) = (pi)(5^2)h
Divide both sides by 25pi.
15 = h
Answer: The height is 15 m.
Answer:

Step-by-step explanation:
The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula

where
B is the area of the triangular face
h is the height of the pyramid
we have

substitute the given values
