WebThe manager wants to know if the proportion of males that prefer ketchup is the same as the proportion of females that prefer ketchup. Test the hypothesis two ways (1) using the Chi-square test and (2) using the z-test for independence with a significance level of 10%. Show how the two test statistics are related and compare the p-values. WebTo determine if we accept or reject the null hypothesis, we need to calculate the Chi Square value and compare it to a critical value at a certain level of significance. With a significance level of 0.05 and 3 degrees of freedom (df = (#rows - 1) * (#columns - 1) = (2-1)*(4-1) = 3), the critical value of Chi Square is 7.815.
WebThe basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true. There are two commonly used Chi-square tests: the Chi-square goodness of fit test and the Chi-square test of independence. Both tests involve variables that divide your data into categories. WebEasy to use critical value calculator for converting a probability value (alpha threshold, a.k.a. significance level) to a Z value, T value, Chi-Square value, or F value using the inverse cumulative probability density function (inverse cumulative PDF) of the respective distribution.
