No, it cannot be used to measure that.

When testings a hypothesis, statistics can be used to calculate the chances or probability of getting a result
To calculate air inclusion during a hydro test, you would measure the volume of air bubbles released during the test using a calibrated container. The volume of air collected can then be compared to the total volume of water used in the test to determine the percentage of air inclusion. This can help assess the integrity of the system being tested.
you take an IQ test!
run each regressors as dependent variable and leave constant as independent variable. in the next window, click down Tests and choose Durbin Watson. This should give you the DW coefficient and its corresponding pvalue. reject null if less than significance level, accept if more than.
Because we have no idea what they are.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate volume of water for hydro test you need to use the formula pi times radius (squared) times length. Pi is equal to 3.14.
You can't. It's impossible.
A chi-square test is often used as a "goodness-of-fit" test. You have a null hypothesis under which you expect some results. You carry out observations and get a set of results. The expected and observed results are used to calculate the chi-square statistic. This statistic is used to test how well the observations match the values expected under the null hypothesis. In other words, how good the fit between observed and expected values is.
