Question

How much do wild mountain lions weigh? Adult wild mountain lions (18 months or older) captured and released for the first time in the San Andres Mountains gave the following weights (pounds):

70

109

126

123

60

64

Assume that the population of x values has an approximately normal distribution.

(a) Use a calculator with mean and sample standard deviation keys to find the sample mean weight x and sample standard deviation s. (Round your answers to one decimal place.)

x =	lb
s =	lb

(b) Find a 75% confidence interval for the population average weight μ of all adult mountain lions in the specified region. (Round your answers to one decimal place.)

lower limit	lb
upper limit	lb

Answer 1

	Values ( X )
	70	484
	109	289
	126	1156
	123	961
	60	1024
	64	784
Total	552	4698

Lower Limit =
Lower Limit = 75.7199
Upper Limit =
Upper Limit = 108.2801

75% Confidence interval is ( 75.7 , 108.3 )
