The fat content (in percentage) of 12 randomly selected hot dogs was measured by scientists:
18.3, 22.6, 28.3, 17.4, 21.6, 22.4, 24.7, 20.9, 29.8, 21.3, 23.6, 25.8
(a) Construct a 95% confidence interval for the population mean fat content. State any
necessary assumptions for your Cl to be valid.
(b) Is there sufficient evidence to conclude that the mean fat content is less than 25%.
You may find the following R code helpful:
x = c(18.3, 22.6, 28.3, 17.4, 21.6, 22.4, 24.7, 20.9, 29.8, 21.3, 23.6, 25.8)

What is the volume of the cone to the nearest cubic millimeter? (use π  = 3.14) a) 46 mm3 b) 128 mm3 c) 183 mm3 d) 275 mm3 diameter = 5 mm height = 7 mm how do you do this problem step by step?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
