Prоvide аn аpprоpriаte respоnse.A lab orders a shipment of 100 rats per week, 52 weeks per year, from a rat supplier for experiments that the lab conducts. Prices for each weekly shipment of rats follow the distribution below: Suppose the mean cost of the rats turned out to be $12.88 per week. Interpret this value.
Prоvide аn аpprоpriаte respоnse.The analytic scores on a standardized aptitude test are known to be normally distributed with mean and standard deviation (a) Draw a normal curve with the parameters labeled.(b) Shade the region that represents the proportion of test takers who scored less than 725.(c) Suppose the area under the normal curve to the left of X = 725 is 0.8413. Provide two interpretations of this result.
Prоvide аn аpprоpriаte respоnse.Giselle bakes six pies a day that cost $2 each to produce. On 35% of the days she sells only two pies. On 38% of the days, she sells 4 pies, and on the remaining 27% of the days, she sells all six pies. If Giselle sells her pies for $5 each, what is her expected profit for a day's worth of pies? [Assume that any leftover pies are given away.]
Prоvide аn аpprоpriаte respоnse.From the probability distribution, find the mean and standard deviation for the random variable x, which represents the number of bicycles per household in a town of 1000 households. 1.
Prоvide аn аpprоpriаte respоnse.A motel has a policy of booking as many as 150 guests in a building that holds 140. Past studies indicate that only 85% of booked guests show up for their room. Find the probability that if the motel books 150 guests, not enough seats will be available. 1.
Prоvide аn аpprоpriаte respоnse.The amount of corn chips dispensed into a 48-ounce bag by a dispensing machine has been identified as possessing a normal distribution with a mean of 48.5 ounces and a standard deviation of 0.2 ounce. What chip amount represents the 67th percentile for the bag weight distribution? Round to the nearest hundredth.
Prоvide аn аpprоpriаte respоnse.The probability that a football game will go into overtime is 16%. In 140 randomly selected football games, what is the mean and the standard deviation of the number that went into overtime?
Prоvide аn аpprоpriаte respоnse.Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Find the probability of at most three girls in ten births.
Prоvide аn аpprоpriаte respоnse.The average score of all golfers for a particular course has a mean of 80 and a standard deviation of 4.5. Suppose 81 golfers played the course today. Find the probability that the average score of the 81 golfers exceeded 81.
