It is believed that the number of drivers who are ticketed for speeding on a particular stretch of highway is a Poisson distribution with a mean of 3.5 per hour. A random sample of 100 hours is selected with the following results:
 
  X Frequency
  0 5
  1 10
  2 20
  3 18
  4 20
  5 15
  6 4
  7 6
  8 1
  9 2
   100
 
  Given this information, and without regard to whether there is a need to combine cells due to expected cell frequencies, the critical value for testing whether the distribution is Poisson with a mean of 3.5 per hour at an alpha level of .05 is x2 = 15.5073.
   Indicate whether the statement is true or false

Question 2
