Rafting down two different rivers took place. 313 boats rafted down the first river, and accidents (capsizing, boat damage, etc.) happened to 32 of them. 97 boats rafted down the second river, and accidents happened to 16 of them. a) The second river is considered to be a more complicated route to raft. Is there evidence for this assumption? Find the P-value of the test. Use a = 0.10.
b) Construct a 90% one-sided confidence limit for the difference in proportions that can be used to answer the question in part (a).

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
