Numerous studies have shown that a high fat diet can have a negative effect on a child's health. A new study suggests that a high fat diet early in life might also have a significant effect on memory and spatial ability. In the double-blind study, young rats were randomly assigned to either a high-fat diet group or to a control group. After 12 weeks on the diets, the rats were given tests of their spatial memory. The article states that "spatial memory was significantly impaired" for the high-fat diet rats, and also tells us that "there were no significant differences in amount of time exploring objects" between the two groups. The \(\mathrm{p}\)-values for the two tests are 0.0001 and 0.7 .

(a) Which p-value goes with the test of spatial memory? Which p-value goes with the test of time exploring objects?

(b) The title of the article describing the study states "A high-fat diet causes impairment" in spatial memory. Is the wording in the title justified (for rats)? Why or why not?
