Question

The current electric Tesla Model S can travel an average of 300 miles on a single charge, μ equals 300 miles, with a presumed population standard deviation, σ, of 40 miles. You are a researcher for the team that is developing a prototype for the next Tesla Model S. Your objective is to produce a vehicle that will be able to be driven significantly more than 300 miles on a single charge. You have conducted a test of your most promising prototype; 100 test drives were made. Here are the results:

---you can see in image(screenshot)

What test statistic should you use?

Step 2. Select the Level of Significance, α

A 5 percent significance level has been selected.

 

Step 3. State the null hypothesis (H0) and alternate hypothesis (H1)

H0:

H1:

 

Step 5. Calculate the Value of the Test Statistic, p-value, Effect Size, and Power

 

 

Step 6: Decide and Report
