Compute the standardized test statistic, chi squaredχ2, to test the claim sigma squaredσ2greater than>3.83.8 if n equals=18, s squareds2equals=5.45.4, and alpha equals 0.01 .α=0.01. Round the test statistic to the nearest thousandth.
Ho : σ² = 3.83
Ha : σ² > 3.83
Level of Significance , α = 0.01
sample Variance, s² = 5.45
Sample Size , n = 18
Chi-Square Statistic X² = (n-1)s²/σ² =
24.19060052
degree of freedom, DF=n-1 = 17
p-Value = 0.114348
as p value > alpha
Do not reject the null hypothesis
