**Exercise: Calculating T-Values**In this exercise, you will find the t-value(s) for various statistical cases. Please round your answers to three decimal places and enter negative values as negative numbers.1. **Upper Tail Area** - Upper tail area of 0.025 with 12 degrees of freedom is ________.2. **Lower Tail Area** - Lower tail area of 0.005 with 55 degrees of freedom is ________.3. **Upper Tail Area** - Upper tail area of 0.20 with 30 degrees of freedom is ________.4. **Middle Range for 90% of Area** - Where 90% of the area falls between these two t-values with 20 degrees of freedom: - ( ________, ________ )5. **Middle Range for 99% of Area** - Where 99% of the area falls between these two t-values with 45 degrees of freedom: - ( ________, ________ )This exercise helps in understanding how to use t-distribution tables or statistical software to determine the critical t-values for specific tail areas and different degrees of freedom.

The upper tail area is 0.025 and the degrees of freedom is 12.

You put n = 20 rats in a cage that is in a room with a 65-degree temperature. The next day you put them in a cage with a 70-degree temperature. On the final day of the study you put them in a cage with a 75-degree temperature. For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel. To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do?
