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):

73 | 108 | 130 | 129 | 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 |
