1. the histogram above represents the number of visitors at the zoo each day in the month of june. what percent of the days had a minimum of 900 visitors? a) 9% b) 21% c) 25% d) 30% e) 70%

Answer

Explanation:

Step1: Find total number of days

June has 30 days. The sum of frequencies in the histogram gives the total number of days considered for the data - collection. From the histogram, the frequencies are 10 + 5+ 6+ 4+ 5 = 30.

Step2: Find number of days with at - least 900 visitors

The intervals with at - least 900 visitors are 900 - 1199 and 1200 - 1499. The frequencies for these intervals are 4 and 5 respectively. So the number of days with at least 900 visitors is 4 + 5=9.

Step3: Calculate the percentage

The percentage of days with at least 900 visitors is calculated using the formula $\frac{\text{Number of days with at - least 900 visitors}}{\text{Total number of days}}\times100%$. Substituting the values, we get $\frac{9}{30}\times100% = 30%$.

Answer:

D. 30%
