In the data set of weights of hummingbirds (in grams) randomly selected from a population, below, what proportion of the observations fall within 1, 2, and 3 standard deviations of each other, and do these figures indicate that the sample may have come from a normally distributed population? A.) 69%, 92%, 100%; yes
B.) 69%, 92%, 100%; no
C.) 50%, 89%, 99%; yes
D.) 50%, 89%, 99%; no
E.) Can't be determined

b

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the answer would be  

a.

3: 1

step-by-step explanation:

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
