The ideal serving temperature of a particular type of red wine in 17 °C. A food critic is worried that even high-profile restaurants are unaware of this important fact and tend to serve this type of wine at a temperature that is too cold. He randomly selects 8 of the best restaurants, orders a bottle of this wine at each place, and measures the serving temperature with a precision thermometer. The mean temperate in his sample is 14.36 °C and the standard deviation is 3.59 °C. The food critic wishes to conduct a test at the .05 level of significance to see if these results provide evidence that the true mean serving temperature is indeed below 17 °C. Calculate the value of the test statistic. (Provide your answer as a number rounded to 3 decimals.)
