Let a = 0.05. Test whether the true variance of blood sugar level is equal to 100 (mg/dl)^2 or not.

Null Hypothesis (Ho): σ2 = 100 (true variance of blood sugar level is equal to 100 (mg/dl)^2)

Alternative Hypothesis (Ha): σ2 ≠ 100 (true variance of blood sugar level is not equal to 100 (mg/dl)^2)

Level of significance = 0.05

R Code is given below:

# chi-square test for variance
varTest(dia\$BloodSugar_mg.per.DL, alternative = "two.sided", conf.level = 0.95, sigma.squared = 100, data.name = NULL)...
