The etiology of high blood pressure remains a subject of active investigation. One widely accepted hypothesis is that excessive sodium intake adversely affects blood-pressure outcomes. To explore this hypothesis an experiment was set up to measure responsiveness to the taste of salt and to relate the responsiveness to blood pressure level. The protocol used involved giving 3 day old infants in the newborn nursery a drop of various solutions, thus eliciting the sucking response and noting the vigor with which they sucked- denoted by MSB (mean number of sucks per burst of sucking). The content of the solution was changed over 10 consecutive periods: (1) water (2) water (3) 0.1 molar salt + water (4) 0.1 molar salt + water (5) water (6) water (7) 0.3 molar salt + water (8) 0.3 molar salt + water (9) water (10) water. In addition, as control, the response of the baby to the taste of sugar was also measured after the salt-taste protocol was completed. In this experiment, the sucking response was measured over 5 different periods with the following stimuli (1) nonnutritive sucking, that is a pure sucking response was elicited without using any external substance (2) water (3) 5% sucrose + water, (4) 15% sucrose + water (5) nonnutritive sucking. The date set for the first 100 infants in attached in a excel format. Construct a variable measuring the response to salt. Obtain descriptive statistics and graphic displays for these salt-taste indices. Do the indices appear to be normally distributed? Why or why not? Compute the sample mean for this index, and obtain 95% Cls about the point estimate.
