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):
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.)
(b) Find a 75% confidence interval for the population average weight of all adult mountain lions in the specified region. (Round your answers to one decimal place.)
Explanation / Answer
The statistical software output for this problem is:
Summary statistics:
One sample T confidence interval:
: Mean of variable
75% confidence interval results:
Hence,
a) x = 93.2 lb
s = 31.6 lb
b) 75% confidence interval:
Lower limit = 76.4 lb
Upper limit = 109.9 lb
