There are three major companies who manufacture gaming consoles. The table below shows that market shares of these three companies, based on last year's global sales figures. Sunny Gameport 50% Purchase intention Marcohard Y-Crate 38% Market share This year, each of these companies is going to launch a new generation of their console. In a survey, a random sample of console owners were asked, which company's new model they are most likely to buy. The results of the survey are show below: Sunny Gameport 143 NineTendons Swap 12% Marcohard Y-Crate 144 NineTendons Swap 60 We can use these data to test whether we have enough evidence that the market shares of the three companies are going to change. Calculate the test statistic which can be used to test the null hypothesis that distribution of current buying intentions among console owners are identical to last year's market shares. (The result must be accurate within +0.05).
