Question 5 (2 points) Suppose that we have a population in which out of every ten US. households, three have no dogs, 4 have 1 dog, 2 have 2 dogs, and 1 has three dogs. The population can thus be represented by a box model [0, 0, 0, 1, 1, 1, 1, 2, 2,3]. The average number, p, of dogs per household then is 1.1 dogs with a standard deviation, 0', of 0.94. Suppose we took a sample of 200 U.S. households. Assume a normal distribution. What is the probability that the total number of households having a dog will be between 180 and 200? Q A) 0.5040 0 B) 0.1336 0 C) 0.0655 0 D) 0.9319 0 E) 0.9345 Question 6 (2 points) For the following box model: [0 1 0 1 0 1 O 0] what is p? O A) 0.30 O B) 0.625 O C) 0.70 O D) 0.80 O E) 0.375 Previous Page Next Page Page 2 0f 4
