here. Chi Square Test Pearson\'s Chisquare Test (19oo) was specifically developed to determine ifobserved deviationsfrom expectation were due to random chance. The null hypothesis of achi square test is that the observed deviations from expectation are due to random chance 25) What is the alternative hypothesis of a chisquare test? Applying the Chi square Test is a multistep process. First you must calculate a squared value (x chi using the following equation 2- observed expected: expected eve of expected number of squa a where is you observed number of events, expected is your co the chi s is the mathematical summation symbol indicating that the Chi value tails, thus heads and events. For example, in a coin toss, there are two possible events,

Solution

the null hypothesis is

Ho: observed deviation from expectation were due to random chance

the alternative hypothesis H1 may be of three type

(1) observed value is more than expected value(one tailed test)

(2) observed value is less than expected value(one tailed test)

(3) observed value is not equal to expected value(two tailed test)
