1. please advice how to work out the figures in the 5th column i.e. (Oi - Ei)22 from that table how do I calculate the Test statistic of X and the critical value of X which we read from the Chi square table3. How do I work out the degrees of freedomPreferably a detailed break down of Chi square calculation with all the step would be preferable I'm trying to learn the various steps of calculating using the Chi square test

Pulling the two tables togelher to get Chi square: \"an the Chi Squire test statistic = 1.789 +1.62? H.060 +0363 +1.615 +1.46? = 3.521 _ I So we calculate {0 E\" for each pan 01' observed and expected values then sum them all up Usmg an onlme calculator we gel X\" = B 5028 {check our calculations on an onllne calculi-Ira) The calculator also gives the value of p = 0 01424 We'll talk aboul [hrs when we get there
