1. Salt-free diets are often prescribed to people with high blood pressure. The following data represents the diastolic blood pressure of eight patients before implementing the diet and after they had followed a salt-free diet for two weeks.

Before 93 106 87 92 102 95 88 110

After 92 102 89 92 101 96 88 105

What would you conclude about the implementation of a salt-free diet based on this data?

Salt-free diets are often prescribed to people with high blood pressure. Eight volunteers participated in a study. Data was obtained from the experiment which was designed to estimate the reduction in diastolic blood pressure as a result of following a salt-free diet for two weeks. Assume diastolic readings are normally distributed.  The resulting mean difference is 1.25mmHg with a standard deviation of 2.4928mmHg.  Construct a 98% confidence interval for the mean reduction in the diastolic reading after two weeks on this diet....

A physician claims that a person's diastolic blood pressure can be lowered if, instead of taking a drug, the person meditates each evening. Ten subjects are randomly selected and pretested. Their blood pressures, measured in millimeters of mercury, are listed below. The 10 patients are instructed in basic meditation and told to practice it each evening for one month. At the end of the month, their blood pressures are taken again. The data are listed below. Test the physician's claim....

The data are not actual data, but are modeled after data collected by Trautwein and Ammerman (2013) for a study on the effects of cochlear implants (CI) on the language, speech, and perception skills of 32 deaf children: 16 subjects with at least one cochlear implant (CI) and 16 subjects (with hearing loss) without an implant. (CI subjects were implanted at 13 or 14 months of age. So, no subjects had CIs at the time of the first data collection.)...
