It has been reported that 7 % of phones manufactured by a certain company for a product launch did not meet the quality standards. An engineer needs at least one defective Phone so she can try to identify the problem(s). If she randomly selects 15 phones from a very large batch, what is the probability that she will get at least 1 that is defective? Is that probability high enough so that she can be reasonably sure of getting a defect for her work? Probability that at least one phone out of a sample of 15 is defective is (round to 4 decimal places). [a] Is the probability high enough so that she can be reasonably sure of getting a defect for her work? Type Yes or No in the box below.  [b]

Read and answer the following question. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 182 lbs and a standard deviation of 30 lbs. An elevator in the health club is limited to 35 occupants, but it will be overloaded if the total weight is in excess of 6860 lbs.Assume that there are 35 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight =  [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b]   round to 2 decimal places   If we assume that 35 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) =  [c] round to 4 decimal places

Suppose you want to estimate the percentage of videos on YouTube that are cat videos. It is impossible for you to watch all videos on YouTube so you use a random video picker to select 1000 videos for you. You find that 5% of these videos are cat videos. Based on the above, identify the following as an observation, a variable, a sample statistic, or a population parameter. a) The percentage of all videos on YouTube that are cat videos. [a] b) 5% [b] c) A video in your sample [c] d) Whether or not a video is a cat video [d]

Kyle and Ryan take entrance exams at two different universities. Kyle scores a 474 on an exam with a mean of 375 and a standard deviation of 68, while Ryan scores a 41 on an exam with a mean of 21 and a standard deviation of 2. Which do you think is more likely to be accepted at the university of his choice? Round to the hundredths place. What is Kyle’s test score as a zscore? [a] What is Ryan’s test score as a zscore? [b] Who is more likely to be accepted at the university of his choice? Type either Kyle or Ryan in the box below.  [c]

[a] What is the probability the card drawn is a 3? [b] What is the probability that the card is a Queen and a 3? [c] What is the probability that the card is a Queen or a 3? [d] What is the probability the card drawn is a face card? [e] What is the probability the card drawn is a heart? [f] What is the probability that the card is a face card and a heart? [g] What is the probability that the card is a face card or a heart? [h]
