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 , 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 ] true or false The study supports his hypothesis that polar bears sleep more on warmer days. true or false
