Tourism is seen as one of the key contributors to national development. The Nepalese tourism industry should be considered to be one of the most important foundations of national economic development and developed accordingly. So the national planning commission of Nepal set the objective: to contribute to the national economy by developing Nepal as one of the most attractive, scenic, and safe tourism destinations in the world, and to increase the flow of tourists both in quality and quantity through the promotion of tourism at the national and international levels and to distribute the benefits they bring justly. To increase the tourist follow in the country it is necessary to motivate and provide the satisfaction to them. It can be believed that satisfied tourists either revisit the same destination or increase their length of stay or recommend the tourist destination to their friends and relatives. As a result tourism industry will be expanded, which can offer opportunities to generate income for business providers and local communities who are living in the area of tourism sites. In the long run, it has a significant contribution to the National GDP. According to tourism statistics in Nepal 2015, Indian tourists ranked 1 and Chinese tourists ranked 2 (on the basis of tourist arrival in Nepal). There is a dilemma what is the length of stay of Indian and Chinese tourists separately. Some hotel owners of the lakeside Pokhara claimed that the average length of stay of Chinese is higher than the average length of stay of Indians. The manager collects the following information regarding the length of stay of some tourists to solve the dilemma but he is a novice, so he has no idea about hypothesis testing. Help him to solve the problem and suggest to him whether the claim of some hotel owner is valid or not.<\/p>\n<table width=\"215\">\n<tbody>\n<tr>\n<td colspan=\"2\" width=\"215\">Length of Stay
