The level of significance, $\alpha =0.05$.
The population variance, ${\sigma }^{2}={0.55}^{2}=0.3025$.
As the null hypothesis, assume that the population variance of petal length is equal to 0.3025 and alternative hypothesis is that the population variance of petal length is greater than 0.3025.
The null hypothesis for testing is defined as,
${H}_{0}:{\sigma }^{2}=0.3025$
The alternative hypothesis is defined as,
${H}_{1}:{\sigma }^{2}>0.3025$
