Rod is a drummer who purchases his drumsticks online. when practicing with the newest pair, he notices they feel heavier than usual. when he weighs one of the sticks, he finds that it is 2.66 oz. the manufacturer's website states that the average weight of each stick is 2.25 oz with a standard deviation of 0.17 oz. assume that the weight of the drumsticks is normally distributed. what is the probability of the stick's weight being 2.66 oz or greater

0.0080

Step-by-step explanation:

Given : The manufacturer's website states that the average weight of each stick is oz with a standard deviation of oz.

We assume the weight of the drumsticks is normally distributed.

Using formula , the z-value corresponds x=2.66 will be :-

By using the standard normal distribution table for z, we get

P-value =

Hence, the probability of the stick's weight being 2.66 oz or greater=0.0080

where are the choices?

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
