Cost per serving (in cents) for six high-fiber cereals rated very good and for nine high-fiber cereals rated good are shown below. Cereals Rated Very Good Cereals Rated Good Compute the lower quartile, median, upper quartile, and interquartile range for the cereals rated very good. (Enter your answers to one decimal place.) lower quartile cents median cents upper quartile cents interquartile range cents Compute the lower quartile, median, upper quartile, and interquartile range for the cereals rated good. (Enter your answers to one decimal place.) lower quartile cents median cents upper quartile cents interquartile range cents Write a few sentences describing how these two data sets differ with respect to center and variability. Use the summary statistics found above to support your statements. The median cost per serving is higher for cereals rated good compared to cereals rated very good. The interquartile range is for cereals rated good compared to cereals rated very good, reflecting a spread in the distribution for cereals rated good.

00:01 Hey there, welcome to numerade.
00:03 We are asked to find a mean quartiles and iqr of the fiber content and the sugar content data set.
00:13 So we're going to start with the fiber content data here.
00:18 So in order to find our certain equations, we're going to be using the percentile rank equation.
00:25 And with we have our percentile times n plus one.
00:30 And term.
00:33 So for example, let's show it for the median first.
00:37 So the median here, what we have is the percentile rank, where the median reflects the 50th percentile.
00:46 So it's going to be multiplied by 18 plus 1, because we have a sample size of 18, equaling 19 divided by 2, which basically equals 9 .5.
00:58 So this basically represents the 9 .5.
01:01 Fifth term corresponding to a median here that equals around eight...
