Question
zack works at stop-n-go campground. he recorded the number of campsites booked for this weekend.
stop-n-go campsites
campsite\trv\ttent\tpop-up
frequency\t9\t11\t5
complete the relative frequency table for the data.
stop-n-go campsites
campsite\trv\ttent\tpop-up
relative frequency\t□%\t□%\t□%
Step1: 计算总频数
总频数为各频数之和,即\(9 + 11 + 5 = 25\)。
Step2: 计算RV的相对频率
相对频率 = (RV的频数÷总频数)×100%,即\(\frac{9}{25}×100\% = 36\%\)。
Step3: 计算Tent的相对频率
相对频率 = (Tent的频数÷总频数)×100%,即\(\frac{11}{25}×100\% = 44\%\)。
Step4: 计算Pop - up的相对频率
相对频率 = (Pop - up的频数÷总频数)×100%,即\(\frac{5}{25}×100\% = 20\%\)。
