question 144

True/False

TABLE 8-7
A hotel chain wants to estimate the mean number of rooms rented daily in a given month. The population of rooms rented daily is assumed to be normally distributed for each month with a standard deviation of 24 rooms. During February, a sample of 25 days has a sample mean of 37 rooms.
-Referring to Table 8-7, we are 99% confident that the average number of rooms rented daily in a given month is somewhere between 24.64 and 49.36.
