Question

A tourism board in Peninsular Malaysia has conducted a survey of small hotels (defined as hotels with 12 or fewer rooms). One of the objectives was to establish the extent to which small hotels used the local tourist information center to obtain bookings. A simple random sampling was conducted from a population of 300 hotels. It was found that of 60 responses received, 45 hotels used the local tourists information center to obtain bookings.

 

Within the same survey, hotel keepers were asked about their room prices. The average price of a single room was RM200 per night and the standard deviations of prices was RM60. The research officer was hoping to estimate the mean room price to within ± RM12. Estimate the smallest achieved sample size with at least 95% confidence.
