an inventor had developed a system that allows visitors to museums, zoos and other attractions to get information at the touch of digital code. For example zoo patrons can listen to an announcement (recorded in a microship about each animal they see. it is anticipated that the device would be rent for ksh3 each the installation cost is sh 400,000. the abc zoo is interested in having the device installed but the management is uncertain about whether to take the risk.A financial analysis of the problem indicates that if more than 10 percent of zoo visitors rent the system the zoo will make profit. To help make the decision a random sample of 400 zoo visitor's is given details of the system capabilities and cost. if 48 people rent the device can the management of the zoo conclude at the 5 percent significance level that the investment would result in a profit
