5-54. Eleven resilient modulus observations of a ceramic mixture of type A are measured and found to have a sample average of 18.42psi and sample standard deviation of 2.77psi. Ten resilient modulus observations of a ceramic mixture of type B are measured and found to have a sample average of 19.28psi and sample standard deviation of 2.41psi. Is there sufficient evidence to support the investigator's claim that type A ceramic has larger variability than type B? Use =0.05
