- A cereal manufacture claims that the gross weight (including packaging) of a box of cereal weight is uniformly distributed between 11.5 oz and 14 oz. You gather 75 boxes and weigh them all together. Let S denote the total weight of 75 boxes of cereal. What is P(S< 930)? Please use the Z-table to provide the answer.Nonecan this be solved without binomial distribution please?
- An arcade machine costs one dollar to play. Every time you play, there is a 1/10 chance of winning.(a) Let A be the number of times you play until you win. Find the variance Var[A].(b) Ten people play the arcade machine; each one keeps playing until they win, and thenit’s the next person’s turn. Let B be the number of times they play in total. Find thevariance Var[B].(c) Ten years later, you come back to the arcade machine, and it’s exactly the same, exceptthat due to inflation, the machine costs $10 to play.Let C be the the total cost of playing until you win. Find the variance Var[C].Will you help me with this one again? When I tried doing it myself, I wasn't getting the correct answers.Compute the power of the test if the researcher uses a sample of n = 4 individuals. The power for the test is the probability of obtaining a z-score than , which corresponds to p = Thus, the power of the test is %. Compute the power of the test if the researcher uses a sample of n = 25 individuals. The power for the test is the probability of obtaining a z-score than which corresponds to p = Thus, the %3D power of the test is 이0.
- please helpIn this unit, three important characteristics of a binomial experiment are summarized: fixed number of trials. two possible outcomes; and n independent trials repeated using the same conditions. Based on the above mentioned characteristics, Think of a binomial experiment example from your own area of interest. Describe how the experiment selected meets all the characteristics of a binomial experiment.
