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): 72 105 132 121 60 64 USE SALT 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 four decimal places.) x = S = lb lb (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.) lower limit upper limit lb lb 2. [-/5 Points] DETAILS BBUNDERSTAT12HS 7.3.016.S. For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. Case studies showed that out of 10,375 convicts who escaped from certain prisons, only 7676 were recaptured. USE SALT MY NOTES ASK YOUR TEACHER (a) Let p represent the proportion of all escaped convicts who will eventually be recaptured. Find a point estimate for p. (Round your answer to four decimal places.) (b) Find a 99% confidence interval for p. (Round your answers to three decimal places.) lower limit upper limit Give a brief statement of the meaning of the confidence interval. We are 1% confident that the true proportion of recaptured escaped convicts falls within this interval. We are 1% confident that the true proportion of recaptured escaped convicts falls above this interval. We are 99% confident that the true proportion of recaptured escaped convicts falls within this interval. We are 99% confident that the true proportion of recaptured escaped convicts falls outside this interval.
