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 19 shift registers, and you record the following shut-down temperatures. Construct a 80% confidence interval for the overall mean shutdown- temperature. 175.18 175.45 174.3 174.98 175.58 174.95 174.2 175.54 174.89 174.41 174.82 175. 175.27 175.1 174.65 175.03 175.71 (Checksum: 3325.78) a) Find the critical value and o.

![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 \(\sigma = 0.4\) degrees Celsius. You test a random sample of 19 shift registers, and you record the following shut-down temperatures. Construct a 80% confidence interval for the overall mean shutdown-temperature.
