Question 11

Students are investigating the effect of temperature on the rate of respiration in yeast. They measured the rate of carbon dioxide production (in $min−1\text{cm}^3\,\text{min}^{-1}$ ) with multiple replicates at $25∘C25^\circ\text{C}$ and $35∘C35^\circ\text{C}$ . The students want to determine whether the mean rate of carbon dioxide production is significantly greater at $35∘C35^\circ\text{C}$ compared to $25∘C25^\circ\text{C}$ .

Which statistical test should they use?

Chi-squared ( $χ2\chi^2$ ) test

Student's $t$ -test

Spearman's rank correlation coefficient

Standard deviation
