An astronomer observes a random sample of 100 pulses of light
from a pulsating star. This resulted in a sample average pulse
duration of 0.81 seconds and a sample standard deviation of 0.34
seconds.
(i) State the distribution of the sample average pulse
duration.
(ii) Calculate a 99% confidence interval for the true average pulse
duration µ.
(iii) Interpret the confidence interval obtained in (ii).
(iv) Calculate the minimum sample size that would be required in
order to estimate the true average pulse duration to within ± 0.05
sec with 95% confidence

It is important that face masks used by firefighters be able to withstand high temperatures because firefighters commonly work in temperatures of 200-500°F. In a test of one type of mask, 9 of 45 masks had lenses pop out at 250°. Construct a 90% upper confidence limit for the true proportion of masks of this type whose lenses would pop out at 250°. (Round your answers to four decimal places.) You may need to...
