ZOOM IN PLEASE I CANT MAKE IT BIGGER
According to a certain golf association, the weight of the golf ball ball shall not be greater than 1.620 ounces (45.93 grams). The diameter of the ball shall not be less than 1.680 inches. The velocity of the ball shall not be greater th 250 feet per second. The golf association periodically checks the specifications of golf balls using random sampling. Two dozen of each kind are sampled, and if more than three do not meet size or velocity requirements, that kind ball is removed from the golf association's approved list. Complete parts a and b a. What assumptions must be made in order to use the binomial probability distribution to calculate the probability that a particularkind of golf ball will be removed? A. The experiment consists of n identical trials. The number of outcomes can vary. The probability of success can change. The trials are independent. O B. The experiment consists of n identical trials. There are only two possible outcomes on each trial. The probability of success can change from trial to trial. The trials are dependent O C. The experiment consists of n identical trials. There are only two possible outcomes on each trial. The probability of success remains the same from trial to trial. The trials are independent What information must be known in order to use the binomial probability distribution to calculate the probability that a particular kind of golf ball will be removed? A. The percentage of that kind of golf ball that meets the velocity requirements O B. The percentage of that kind of golf ball that meets all the requirements C. The percentage of that kind of golf ball that meets the size requirements 0 D. The percentage of that kind of golf ball that fails to meet both size and velocity requirements b. Suppose 15% of all balls produced by a particular manufacturer are less than 1.680 inches in diameter and assume that the number of such balls. x in a sample of two dozen balls can be adequately characterized by a binomia probability distribution. Find the mean of the binomial distribution. -D (Round to the nearest tenth as needed.) Find the standard deviation of the binomial distribution. :D (Round to the nearest thousandth as needed.)Explanation / Answer
in order to choose binomail probaility distrubution to calculatr the probability of the particular kind of golf ball is removed we can choose the assumption that the experiment comsists of the n identical trails .there are only two possible outcomes on each trail .that is either true or flase the probability od=f the sucess remains the same from the trail to trail the trails are indepedent
to use the binomial distribution of the such kind of the distribution we must meet the percentage of the that kind of golf ball that meets the size requirements
lets consider that the number of trails is 100
the sucess prbability is 0.15
then the number of sucess trails is 15
then the binomial probability is 0.1111
the mean is 0.156*100=15
