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 45 49 62 42 18 78 Cereals Rated Good 74 30 51 51 USE SALT 66 44 46 29 55 Compute the lower quartile, median, upper quartile, and interquartile range for the cereals rated very good. lower quartile 35.75 median 46.5 upper quartile interquartile range 66.25 30.5 cents X cents X cents X cents Compute the lower quartile, median, upper quartile, and interquartile range for the cereals rated good. lower quartile 36 X cents median 51 cents upper quartile 61 cents interquartile range 25 cents X 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 higher for cereals rated good compared to cereals rated very good, reflecting a greater spread in the distribution for cereals rated good.

The accompanying data represent the actual amount (in mL) poured into a short, wide glass for individuals asked to pour 44.3 mL (1.5 ounces). 89.1 68.6 32.9 37.2 39.6 46.9 66.2 79.2 mean 64.3 53.7 63.2 46.2 63.0 92.4 57.6 USE SALT 66.4 (a) Calculate the values of the mean and standard deviation (in mL). (Round your answers to four decimal places.) mL mL standard deviation 52.2 47.2 Interpret the values of the mean and standard deviation. (Round your answers to four decimal places.) A typical amount poured into a short, wide glass is mL. A typical deviation from the mean amount poured is mL. (b) The mean amount poured into a tall, slender glass for individuals asked to pour 44.3 mL (1.5 ounces) was 51.3389 mL. What do the values of the means for the two types of glasses suggest about the shape of glasses used? the mean amount for a tall, slender glass. This suggests that individuals tend to pour |---Select--- into a short, wide glass compared to a tall, The mean amount for a short, wide glass is ---Select--- slender glass.
