You work for a company that produces electronics with integrated circuits. One of your products is called a "shift register." This product is designed to automatically shut down if its operating temperature exceeds 175 degrees Celsius. The manufacturing process has been designed to have a standard deviation of o = 0.4 degrees Celsius. You test a random sample 18 shift registers, and you record the following shut- down temperatures. Construct a 95% confidence interval for the overall mean shutdown-temperature. 174.7 174.66 175.46 175.29 174.47 175.69 174.81 174.44 174.85 175.41 174.68 174.88 174.95 174.89 174.8 175.04 175.54 174.44 (Checksum: 3149) a) Find the critical value and og .

Question 6: You work for a company that produces electronics with integrated circuits.  One of your products is called a "shift register."  This product is designed to automatically shut down if its operating temperature exceeds 175 degrees Celsius.  The manufacturing process has been designed to have a standard deviation of σ=0.4σ=0.4 degrees Celsius.  You test a random sample 18 shift registers, and you record the following shut-down temperatures. Construct a 95% confidence interval for the overall mean shutdown-temperature.
