which is a common value. We are now ready to calculate a test statistic; in this case, we'll use thechi-square statistic.The procedure for calculating this statistic is outlined as
Chi-square is a non-parametric test, i.e., it does not require normal distribution or variance assumptions about the populations from which the samples are drawn. The general purpose of the…

If the chi-square statistic that we calculate from our data is greater than or equal to19.675, then we reject the null hypothesis at 5% significance. If our chi-square statistic is less than 19.675, then wefail to rejectthe null hypothesis....

Calculate the T-statistic Step 1 Subtract the population mean from the sample mean: x-bar –μ. Step 2 Divide s by the square root of n, the number of units in the sample: s ÷√(n). Step 3 Take the value you got from subtracting μ from x-bar and divide it by the value you...
It can also be used to test the goodness of fit between an observed distribution and a theoretical distribution of frequencies. Formula for a Chi-Square (χ2) Statistic χc2=∑(Oi−Ei)2Eiwhere:c=Degrees of freedomO=Observed value(s)E=Expected value(s)\begin{aligned}&\chi^2_c = \su...
