30% of the sampled students <u>have three or more siblings</u> at home.

<u>Step-by-step explanation</u>:

<u>step 1</u> : The total number of students sampled = 20 students.

<u>step 2</u> : The students having three or more siblings = 6 students.

The question asks for what percentage of the sampled students have three or more siblings.

<u>step 3</u> : Let the unknown percentage be X%

X% of total sampled student = students having 3 or more siblings

(X/100) \times 20 = 6 students.

2x = 6\times10

x = \frac{60}{2}

x = 30 %

With the given hint to be able to answer the question above, the equation for Newton's law of cooling is as follows:
                         T(t) = T(s) + (T0 - Ts)e^-kt
where T(t) is the body's temperature at any given time, Ts is the temperature of the surrounding, T0 is the initial temperature, and k is constant. 
Substituting the values with the given above,
                             T(t) = 76 + (170 - 76)*e^(-0.34)(7)
This gives us the answer,
                                     T(t) = 84.7 degrees F
