The owner of a local nightclub has recently surveyed a random sample of 300 customers of the club. She would now like to determi
ne whether or not the mean age of her customers is over 35. If so, she plans to alter the entertainment to appeal to an older crowd. If not, no entertainment changes will be made. Suppose she found that the sample mean was 35.5 years and population standard deviation was 5 years. What is the p-value associated with the test statistic
First walk=descend of 1024 feet in 17 minutes second walk=descend of 500 feet in 7 minutes
so in total she descended 1024+500=1524 feet in 7+17=24 minutes as an average rate this equals 1524/24=63.5 feet/minute descended or an average rate of -63.5 feet/minute in altitude (note the minus)
