A researcher at the Lincoln Park Zoo is testing the hypothesis that a polar bears sleep more on warmer days. He uses his data to estimate the following regression equation: = 340 +2.75x, where y is the number of minutes a polar bear sleeps in a 24 hour period, and x is the temperature (in degrees Fahrenheit) at 12:00pm. The 95% confidence interval for B, the coefficient of x, is (1.25, 3.87). Based upon this study, the researcher can reject the null hypothesis that polar bear sleep is not affected by the daily temperature. [Select] The study supports his hypothesis that polar bears sleep more on warmer days. [Select]
