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 19 shift registers, and you record the following shut-down temperatures. Construct a 95% confidence interval for the overall mean shutdown-temperature. 175.39 174.24 174.88 174.83 174.77 174.29 174.53 175.3 174.52 174.86 175.04 175.72 174.82 174.93 174.61 175.33 174.91 175.02 174.96 (Checksum: 3322.95) a) Find the critical value and σ¯xσx¯ . Critical Value: ____ σ¯xσx¯ : ______ b) Find the confidence interval: (,)
