Because the mean is very sensitive to extreme values, it is not a resistant measure of center. By deleting some low values andhigh values, the trimmed mean is more resistant. To find the 10% trimmed mean for a data set, first arrange the data in order, thendelete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values.

Knowing the physical properties, such as shape, size, and density, is critical for designing equipment for harvesting, handling, processing, and storage of food materials. Shape and size parameters such as the major, minor, and intermediate diameter and geometric mean diameter are important for designing sorting, cleaning, and packaging equipment. Calculate the geometric mean diameters (in millimeters) from the physical property data given in Table 1 for a variety of mango (Irvingia gabonesis) and plum (Prunus domestica). Table 1. Measured physical property data for mango fruit, Irvingia gabonesis, and plum, Prunus domestica (adapted from Ehiem & Simonyan, 2012; Nazari and Rashidi, 2014) Parameter Irvingia gabonesis Prunus domestica Major diameter (mm) Intermediate diameter (mm) Minor diameter (mm) 66.3 66.1 60.5 45.8 45.1 42.2
"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle recovery angle" measures how well a fabric recovers from wrinkles. Higher is better.

A local authority is going to study the relationship between the size of household and the daily plastic usage consumed by them. The results of a sampling given below in Table 5 indicate some values of X (weight of plastic usage) and Y (the size of household).

The pathogen Phytophthora capsici causes bell peppers to wilt and die. Because belI peppers are an important commercial crop, this disease has undergone a great deal of agricultural research. It is thought that too much water aids the spread of the pathogen. Two fields are under study. The first step in the research project is to compare the mean soil water content for the two fields. Units are percentage of water by volume of soil. Field A samples, x: 10.0 10.7 15.5 10.4 9.9 10.0 16.6 15.1 15.2 13.8 14.1 11.4 11.5 11.0 Field B samples, x,: 8.3 8.5 8.4 7.3 8.0 7.1 13.9 12.2 13.4 11.3 12.6 12.6 12.7 12.4 11.3 12.5 A USE SALT Use a calculator to calculate x,, s,,x,, and s,.
