Question

2. Barry asked 40 random students at his school to name their favorite ice cream flavor. Of the 40students he asked, 25 of them preferred chocolate. Based on Barry's results, how many of the1,200 students in the school most likely prefer chocolate ice cream?(1 poin2004507501,000

Answer 1

From Barry's experiment,

`\begin{gathered} \text{Percent that prefered chocolate=}(25)/(40)*100 \\ \text{Percent that prefered chocolate=}(2500)/(40) \\ \text{Percent that prefered chocolate=62.5\%} \end{gathered}`

Therefore, we can use this experiment to deduce that 62.5% of the total 1,200 student population prefered chocolate ice cream. Hence, we would have,

`\begin{gathered} \text{Percent that prefered chocolate=}(62.5)/(100)*1200 \\ Percent\text{ that prefered chocolate=0.625x1200} \\ P\text{ercent that prefered chocolate=750 } \end{gathered}`

The result of Barry's experiment shows that 750 students in the school most likely prefer chocolate ice cream
