Chi-squared test. A chi-squared test, also written as Ï 2 {\displaystyle \chi ^{2}} test, is any statistical hypothesis test wherein the sampling distribution of the test statistic is a chi-squared distribution when the null hypothesis is true.
volcanoes can also occur at hot spots such as at the areas of the hawaiian islands and yellowstone in america this type of volcano forms when magma from the mantle rises to earth s surface through a certain spot in the middle of the plate i e the pacific plate for the hawaiian islands
Answer 1: Volcanos are most commonly found at subduction zone boundaries. This is where the thinner oceanic plates get pulled under the thicker continental plates. As the plates go deeper, they melt and form pockets of magma which can cause mountains to be built and as the hot magma rises, it erupts out of volcanos.sually volcanoes are found near subduction zones, where oceanic crust sinks beneath continental crust. In fact, they're quite often about 200 km inland (on the continental plate) from where the subducting plate sinks below the overriding plate.
