To find out approximately how many minutes students in a high school are spending texting while in class, the guidance counselor
conducts a carefully designed and implemented random survey. The table below shows the number of minutes per week these randomly selected students text in class. Minutes Per Week Students Text in Class
What is the estimated number of minutes per week all students in this school, the population mean, text while in class based on the sample, rounded to the nearest tenth of a minute?
30. Answer if u place the equation into a fraction: example 20/8 yellow over red. Next let’s put the other amount into a fraction, we don’t know yellow so for the fraction we will put x: x/18. For our next step we will then cross multiply 20 by 18 and 8 by x getting 8x=360 from there you divide for x getting 45 yellow.
