3. A published article contains a statistical analysis of historical summer precipitation data in relation to summer temperatures using individual t tests for 121 locations at the 10% level. The study investigates the null hypothesis of no difference in total precipitation between the 10 warmest summers in the period 1900-1969 and the remaining 60 summers, reports that 15 of the 121 tests exhibit significant results, and claims that the overall pattern is therefore significant. Evaluate this claim.
