Question

Let x be a random variable representing dividend yield of bank stocks. We may assume that x has a normal distribution with ? = 2.5%. A random sample of 10 bank stocks gave the following yields (in percents).

  • 5.7  
  •  
  • 4.8  
  •  
  • 6.0  
  •  
  • 4.9  
  •  
  • 4.0  
  •  
  • 3.4  
  •  
  • 6.5  
  •  
  • 7.1  
  •  
  • 5.3  
  •  
  • 6.1

The sample mean is  = 5.38%. Suppose that for the entire stock market, the mean dividend yield is ? = 4.9%. Do these data indicate that the dividend yield of all bank stocks is higher than 4.9%? Use ? = 0.01.

 

(c)

 Find (or estimate) the P-value. (Enter a number. Round your answer to four decimal places.) ?


Sketch the sampling distribution and show the area corresponding to the P-value. (Select the correct graph.)
