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, 11 of 55 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.) (0.1113 x 0.2887 x ) You may need to use...

Answer the following question
A random sample of 103 lightning flashes in a certain region resulted in a sample average radar echo duration of 0.77 sec and a sample standard deviation of 0.36 se Calculate a 99% (two-sided) confidence interval for the true average echo duration p. (Round your answers to two decimal places.) Interpret the resulting interval We are 99% confident that this interval does not contain the true population mean. O We are 99% confident that the true...

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, 11 of 55 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.) (0.1113, 0.2887) is incorrect. I need help figuring out why.

A random sample of 109 lightning flashes in a certain region resulted in a sample average radar echo duration of 0.82 sec and a sample standard deviation of 0.41 sec. Calculate a 99% (two-sided) confidence interval for the true average echo duration u. (Give answers accurate to 3 decimal places.)

4. It is important that face masks used by firefighters be able to withstand high tem- peratures because firefighters commonly work in temperatures of 200-500 degrees. pop out one t of masK, 55 were found to have their lenses at 325 degrees. Construct and interpret a 90% confidence interval for the true proportion of masks of this type whose lenses would pop out at 325 degrees.

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°.

Answer the following question
A journal article reports that a sample of size 5 was used as a basis for calculating a 95% CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (230.061, 233.807). You decide that a confidence level of 99% is more appropriate than the 95% level used. What are the limits of the 99% interval? (Hint: Use the center of the interval and its width to determine...
