The town of KnowWearSpatial, U.S.A. operates a rubbish waste disposal facility that is overloaded if its 4771 households discard waste with weights having a mean that exceeds 27 lb/wk. For many different weeks, it is found that the samples of 4771 households have weights that are normally distributed with a mean of 26.74 lb and a standard deviation of 12.18 lb.What is the probability that the disposal facility is overloaded in a randomly selected week?P( ¯xx¯ > 27) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.Is this an acceptable level, or should action be taken to correct a problem of an overloaded system? No, this is not an acceptable level because it is not unusual for the system to be overloaded. Yes, this is an acceptable level because it is unusual for the system to be overloaded.
The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. Click the icon to view the table. a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 1 or fewer girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? *** O A. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. OB. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. OC. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the…

A researcher wanted to study the commuting habits of community college students and faculty. He wanted to compare their mode of transportation to the college. He asked if they walk, bike, or drive to campus. The following table represents the data that was collected. Walks to campus Bikes to campus Drives to campus Total Students 70 22 78 170 Faculty 5 4 23 32 Total 75 26 101 202 A. Find the probability that a randomly selected member of faculty walks to campus. B. If you are randomly selecting a person from those who bike to campus, what is the probability that you will select a student. C. Perform a Test of Independence to determine if commuting habits are dependent on being a student or a faculty.
