In Moab, Utah, temperature and rainfall exhibit a correlation of .67. Assuming that this correlation is significant (not due to chance), is there more rainfall, on the average, in the summer or in the winter at this location?

Among a population of tadpoles, the correlation coefficient for size at metamorphosis and time required for metamorphosis is — .74. On the basis of this correlation, what conclusions can you make about the relative sizes of tadpoles that metamorphose quickly and those that metamorphose more slowly?
