Step-by-step explanation:
Given
A proportional relation is given between minutes spend in reading and no of pages
Suppose we choose the point , It shows that 2 minutes is taken to read three pages.
Similarly, for point , It shows four minutes is taken to read 6 pages.
In this way, 6 minutes is taken for 12 pages.
Answer: 72.78% of the drivers are traveling between 70 and 80 miles per hour based on this distribution.
Step-by-step explanation:
Let X be a random variable that represents the speed of the drivers.
Given: population mean : M = 72 miles ,
Standard deviation: s= 3.2 miles
The probability that the drivers are traveling between 70 and 80 miles per hour based on this distribution:
Hence, 72.78% of the drivers are traveling between 70 and 80 miles per hour based on this distribution.
