The yield of a chemical process is being studied. From previous experience, yield is known to be normally distributed and σ = 3. The past 5 days of plant operation have resulted in the following percent yields: 91.6, 88.75, 90.8, 89.95, and 91.3. Find a 95% two-sided confidence interval on the true mean yield.

In the 16/17 season, Valencia CF (Spanish soccer club) had 19 home games.

A manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed with standard deviation 0.3 volt, and the manufacturer wishes to test volts against volts, using n=16 units. The acceptance region is . Find the value of .

Medical researchers have developed a new artificial heart constructed primarily of titanium and plastic. The heart will last and operate almost indefinitely once it is implanted in the patient’s body, but the battery pack needs to be recharged about every 4 hours. A random sample of 50 battery packs is selected and subjected to a life test. The average life of these batteries is 4.05 hours. Assume that battery life is normally distributed with standard deviation σ = 0.2 hour. Is there evidence to support the claim that mean battery life exceeds 4 hours? Use α = 0.05. What is the P-value for the test?
