The State Department of Forests has determined that annual tree growth in a particular forest area is normally distributed with a mean equal to 17 inches and a standard deviation equal to 6 inches.
 
  Based on this information, it is possible for a randomly selected tree not to have grown any during a year. Indicate whether the statement is true or false

Question 2

Test the hypotheses that between-group means are equal. Use  = 0.05.
 
  What will be an ideal response?

Answer to Question 1

TRUE

Answer to Question 2

H0 : 1 = 2 = 3 = 4 = 5 = 6
H1 : i  j for at least one pair (i, j)
Reject H0 if F > F5, 25, 0.05 = 2.60. Since F = 4.91, H0 is rejected at  = 0.05. We conclude that at least two of the six between-group means are not the same.
