8. | Agriculture: Harvest Weight of Maize The following data represent weights in kilograms of maize harvested from a random sample of 72 experimental plots on St. Vincent, an island in the Caribbean (Reference: B. G. F. Springer, Proceedings of the Caribbean Food Crops Society, Vol. 10, pp. 147–152). Note: These data are also available for download at http://www.cengagebrain.com. For convenience, the data are presented in increasing order. 7.8 9.1 9.5 10.0 10.2 10.5 11.1 11.5 11.7 11.8 12.2 12.2 12.5 13.1 13.5 13.7 13.7 14.0 14.4 14.5 14.6 15.2 15.5 16.0 16.0 16.1 16.5 17.2 17.8 18.2 19.0 19.1 19.3 19.8 20.0 20.2 20.3 20.5 20.9 21.1 21.4 21.8 22.0 22.0 22.4 22.5 22.5 22.8 22.8 23.1 23.1 23.2 23.7 23.8 23.8 23.8 23.8 24.0 24.1 24.1 24.5 24.5 24.9 25.1 25.2 25.5 26.1 26.4 26.5 26.7 27.1 29.5 (a) Compute the five-number summary. (b) Compute the interquartile range. (c) Make a box-and-whisker plot. (d) Interpretation Discuss the distribution. Does the lower half of the distribu- tion show more data spread than the upper half?

A:

Q: If 2*+l = 3-* then find the value of x

A:

Q: olve accordingly

A: we can see that the graph touches at 4 places on the x-axis.

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
