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 91 males and 109 females in their country. The mean and standard deviation of the spleen lengths for the males were 11.3 cm and 0.8 cm, respectively, and those for the females were 10.3 cm and 0.7 cm, respectively. Determine a 95% confidence interva for the difference between mean spleen lengths of males and females in this country. Click here to view page 1 of the table of critical values of t. Click here to view page 2 of the table of critical values of t. Let population 1 be all males in the country and let population 2 be all females in the country. The 95% confidence interval for p, -H2 is (OD (Round to three decimal places as needed. Use ascending order.)
