5. University XYZ has two campuses, the main campus is in Manila and the satellite campus is in Caloocan City. A driver of the university needs to transport documents from the main campus to the satellite campus using the shuttle bus several times in a month. The transport takes on an average of 45 minutes with a standard deviation of 8 minutes. In a given month, the driver transports documents 50 times. In a certain transport of a certain day: a. what is the probability that the transport time will be exactly 40 minutes? b. what is the probability that the transport time will be less than 45 minutes? c. what is the probability that the transport time will be more than 45 minutes? 6. Based from the record of ABC Maternity Hospital, the mean weight of one month old babies is 8 Ibs with a standard deviation of 2 Ibs. Out of 50 one month old babies, find: a. the probability that the mean weight is less than 1 1 1bs b. the probability that the mean weight is equal to 8.5 Ibs c. the probability that the mean weight is greater than 8 Ibs d. the probability of the sample mean is between 6 to 10 lbs1. Find the parameters / and o for the finite population 12, 14, 15, 16, and 20. a. Solve the mean and the standard deviation of the population. b. Set up a sampling distribution of the means and the standard deviations with a sample size of 2 without replacement. c. Show that the sampling distribution of the sample means is an unbiased estimator of the population mean
