Answer 1

Answer:

8.5 hrs

Step-by-step explanation:

-A 75th percentile mathematically means that  75% of the time data points are below that value and 25% of the time are above that value.

-We plot the given our data {3 12 2 3 5} to determine the 75th percentile

#We can use $alcula.com$ to plot our boxplot.

-From the plot, we find our 75th percentile to be 8.5 hrs

Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.
