A test was performed to estimate the level of distress of a sample of male patients and a sample of patients shortly before performing the same surgery. The sizes of the samples and the variances calculated from the obtained scores
They are the following:
Men: n = 13, s2 = 150
Women: n = 21, s2 = 275
Do these data provide sufficient evidence to indicate that, in the populations represented, the scores obtained by women are more variable than those obtained by men? Note: the probability of not rejecting true H0 equal to 0.90 and the probability of rejecting false H0 equal to 0.95.

Researchers studied symptom distress and palliative care designation among a sample of 710 hospitalized patients. Controlling for age, they used a t-test to compare average distress from nausea scores in men and women. Lower scores indicated less distress from nausea. They report men had an average score of 1.02 and woman had an average score of 1.79. Which statement is correct? men had significantly less distress from nausea. Men had half as much distress from nausea as woman but we...

As a researcher, your goal is to estimate the effect of a drug on test scores of human subjects undertaking a test in Statistics. All subjects were divided into two populations X and Y , with members of population X receiving the drug prior to testing and members of population Y receiving a placebo prior to testing. 16 subjects were chosen randomly from population X and the mean score in this group was equal to 9.78, with the sample standard...

For the following test, assume that the two samples are independent simple random samples selected from normally distributed populations and that the population standard deviations are equal (1 = 02) so that the standard error of the difference between means is obtained by pooling the sample variances.
