Objectives. This study aimed to clarify the relationship between community water fluoridation (CWF) and intelligence (IQ) in New Zealand. Methods. We conducted a study of a general population sample of those born in Dunedin, New Zealand, between April 1, 1972, and March 30, 1973 (95.4% retention after 38 years of followup). Residence in a CWF area, use of fluoride dentifrice and intake of 0.5milligram fluoride tablets were assessed in early life (prior to age 5 years); we assessed IQ repeatedly...

15) Which of the following statements are true? I. If a population parameter is known, there is no reason to run a hypothesis test on that population parameter. II. The P -value can be negative or positive depending upon whether the sample statistic is less than or greater than the claimed value of the population parameter in the null hypothesis. III. The P -value is based on a specific test statistic so it must be chosen before an experiment is...
