b. 7
c. (b) Kira's
why? b. it has the large sample size
Step-by-step explanation:
Answer:
a. at zero years of education, income equals $1500
Step-by-step explanation:
The equation for income 'I', as a function of years of education 't' is given by:
Where b is the regression coefficient and a is the intercept.
The intercept is the value assumed by the function for t = 0 years of education:
Since the income function measures income in $1,000s, at zero years of education, income equals $1500
For this case we have the following conversions:
1 yard = 3 feet
The estimate distance Is:
400yd = 1200feet
200yd=600 feet
Ten, the estimate Is:
1200 + 600 = 1800 feet
The real distance Is:
The total distance in yards is given by:
440 + 220 = 660 yd
Then, let's transform this distance to feet, with the given conversion:
660 * 3 = 1980 feet
The distance traveled is reasonable for a person
Comparing the estimate and the actual answer, the distance malcom Ran Is reasonable.
Answer:
Malcolm ran 1980 feet.
The distance is reasonable.
