Standard deviation (σ) = 4.9 mpg
In a normal distribution, for any length X, the z-score is determined by the following expression:
In a normal distribution, the 25th percentile (first quartile) of a normal distribution has a corresponding z-score of z = -0.677 and the 75th percentile has a corresponding z-score of z = 0.677
a. The first quartile of the distribution of gas mileage is
19.68 miles per gallon.
b. The third quartile of the distribution of gas mileage is
26.32 miles per gallon.
Answer:
a) Rate of increase = 26.66 millions per year
b) Rate of increase = 42.64 millions per year
c) Rate of increase = 79.53 millions per year
Step-by-step explanation:
We are given that population is modeled with the exponential function:
where t = 0 corresponds to the year 1900 and P(t) is measured in millions.
Rate of increase of world population =
a) 1920
Rate of increase = 26.66 millions per year
b) 1955
Rate of increase = 42.64 millions per year
c) 2000
Rate of increase = 79.53 millions per year
