2. One-third of drivers never travel more than 50 miles per day.
3. 50% of drivers travel less than 350 miles per week.    
4. One-third of drivers never travel more than 400 miles per week.  

Answer 1

Using the miles driven data, test the following claims:

Put the data in excel and calcuate the following as shown in the screenshot. The inital screen shot is the overview of the entire sheet. Follow by that are parts of each to show you the formula to be use.

50% of drivers travel less than 40 miles per day.

In the data we find that 23 out of 42 person drive less than 40 miles per day.

From the hypothesis testing, we reject the claim that 50% of drivers travel less than 40 miles per day.

One-third of drivers never travel more than 50 miles per day.
In the data we find that 27 out of 42 person drive less than 50 miles per day.

From the hypothesis testing, we reject the claim that one-third of drivers never travel more than 50 miles per day.

50% of drivers travel less than 350 miles per week.
In the data we find that 27 out of 42 person drive less than 350 miles per day.

From the hypothesis testing, we fail reject the claim that 50% of drivers travel less than 350 miles per week

One-third of drivers never travel more than 400 miles per week.
In the data we find that 33 out of 42 person drive less than 400 miles per day.
We reject this claim.
