Researchers from a certain country were interested in how characteristics of the spleen of residents in their tropical environment compare to those found elsewhere in the world. The researchers randomly sampled 93 males and 107 females in their country. The mean and standard deviation of the spleen lengths for the males were 112 cm and 0.9 cm, respectively, and those for the females were 10.3 cm and 0.7 cm, respectively. At the 5% significance level do the data provide sufficient...
