Unformatted text preview: Based on the data, in a random sample of 10 what is the expected number of bad bars? How likely is it that you will see at least 6 bad bars in a random sample of 10? 12. Again, for the Clark Data Set, suppose I define the random variable X as follows: Weight <45 gms. (grossly underweight) ⇒ X=-2 45 ≤ weight<49.6 (underweight) ⇒ X=-1 49.6 ≤ weight ≤ 53.0 (acceptable) ⇒ X=0 53.0<weight ≤ 56.5 (overweight) ⇒ X=1 56.5<weight (grossly overweight) ⇒ X=2 Determine the probability mass function for X and compute and interpret its expected value....
