Two statistics teachers both believe that each has the smarter class. to put this to the test, they give the same final exam to their students. a summary of the class sizes, class means, and standard deviations is given below: n1=53,n2=46,x¯1=87.6,x¯2=79.8,s1=15 .8s2=17.7 n1=53,x¯1=87.6,s1=15.8n2=46,x¯2=79. 8,s2=17.7 is there evidence, at an α=0.05α=0.05 level of significance, to conclude that there is a difference in the two classes? carry out an appropriate hypothesis test, filling in the information requested.

2 is the final ! : )

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

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 !

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
