Temperature and Jumping Performance
A study was done on spotted grass frogs to see whether temperature affects their jumping performance.
Twenty frogs were randomly selected to be kept under a temperature-regulated structure (TRS). Twenty similar frogs were randomly selected and kept separately in normal atmosphere (NA). The selected frogs were of the same age range. The frogs, were observed for 30 days.
Jumping performance improved in two NA frogs whereas the performance improved in 15 TRS frogs.
a. What percentage of the NA frogs and the TRS frogs in the sample showed improved jumping performance? Compare these percentages and comment.
b. Create a two-way table showing the observed values. Label the columns (across the top) with TRS and NA.
c. Test the hypothesis that the temperature is associated with jumping performance (at the 0.05 level of significance).
