Explanation:

Sampling from a population is used when the population is too large to collect data from everyone or if getting data from everyone is impractical. The goal when sampling from a population is therefore to get as representative a sample as you can collect. You don't want to over-represent some groups and/or under-represent other groups as this doesn't allow your sample to describe your population well. In addition to this main goal, statisticians also aim to reduce variability within the sample.

In an experiment the sorption was measured for a variety of hazardous organic chloroalkane solvents. The sample measurements were; 1.18, 1.35, 0.57, 1.16, 1.12, 0.91, 0.83, 0.43 Assuming that measurements are normally distributed.

i) What is the mean of the sample for sorption of chloroalkane solvents.

ii) What is the standard error of the mean for the sample of organic chloroalkane solvents?

iii) What the margin of error of the 99% confidence intervals for the population mean of sorption of chloroalkane solvents.

iv) What is the lower limit for the 99% confidence intervals for the population mean of sorption of chloroalkane solvents.

1) In using chi-square for testing the independence of variables, larger calculated values for chi-square will tend to make it more likely that the null hypothesis will be rejected.

True or False?

a) A contingency table for two nominal variables has three (3) row and four (4) columns. The number of degrees of freedom associated with the chi-square test of variable independence will be df= 6.

True or False?

b) In carrying out chi-square analysis, if one or more of the observed frequencies is less than five (5), rows or columns should be combined so that each value of observed frequency is at least 5.
