Answer

Explanation:

Step1: Calculate mean of swim practice times

Sum of swim times: $55 + 50+70 + 75+60+55+55+75+65+70=635$. Mean of swim times $\bar{x}_{swim}=\frac{635}{10}=63.5$.

Step2: Calculate mean of band practice times

Sum of band times: $45 + 60+90+35+40+50+90+40+45+50 = 545$. Mean of band times $\bar{x}_{band}=\frac{545}{10}=54.5$.

Step3: Analyze the statements

Since $63.5>54.5$, Maggie's daily time at swim practice tends to be greater than her time at band practice.

Answer:

Maggie’s daily time at swim practice tends to be greater than her time at band practice.
