Answer:
a.
b.
c. Choice A- Based on limits above, it is unlikely that we would see x = 45, so it might be possible that the trials are not independent.
Step-by-step explanation:
a.Binomial distribution is defined by the expression
Let n be the number of trials,
and p be the probability of success,
The mean of a binomial distribution is the probability x sample size.
b.Limits within which p is approximately 95%
sd of a binomial distribution is given as:
Therefore,
Use the empirical rule to find the limits. From the rule, approximately 95% of the observations are within to standard deviations from mean.
Hence, approximately 95% of the observations are within 7.8586 and 22.1414 (areas of infestation).
c. is not within the limits in b above (7.8586,22.1414). X=45 appears to be a large area of infestation. A.Based on limits above, it is unlikely that we would see x = 45, so it might be possible that the trials are not independent.
The angle of depression made by the bird to the mouse is seen on the attached image. We can find the distance from the field mouse up to the bird's eye by getting the hypotenuse of the triangle formed. Using the CAH in Pythagorean Theorem, we will have:
cos ∅ = adjacent / hypotenuse
cos 65 = 30 / h
h = 70.98 ≈ 71 m ⇒ the answer is D
cos ∅ = adjacent / hypotenuse
cos 65 = 30 / h
h = 70.98 ≈ 71 m ⇒ the answer is D
