For each scenario, tell what the real limits of the number/interval are:
a. If a person’s temperature is reported as 100.3 (and not 100.2 or 100.4), what is the interval within which the person’s temperature really falls?
b. If a family has 7 children, not 6 or 8, what is the interval within which the number of children they have really falls?
c. If a person’s IQ is reported as 115 (and not 114 or 116), what is the interval within which the person’s IQ has really falls?
d. If nations’ populations are reported to the nearest million and the United States has a population of 311 million, not 310 or 312, how many people really live in the United States?
e. If a man has 3 televisions in his house, not 4 or 5, what is the interval within which the number of televisions he has really falls?
