A researcher claims that the variance of the heights of all female college basketball players is 4.80 square inches. A random sample of 28 female college basketball players produced a variance of their heights equal to 11.122 square inches. The null hypothesis is that the variance of the heights of all female college basketball players is equal to 4.80 square inches and the alternative hypothesis is that the variance of the heights of all female college basketball players is not equal to 4.80. Assume that the population is normally distributed. The significance level is 5%.
