Killer bees have migrated into this country. There is fear that they will spread across the nation. However, they
cannot survive in cold climates. It is thought that they cannot tolerate temperatures below 36 degrees F. T o test this claims random sample of 9 killer bee hives were subjected to colder and colder temperatures until they died. Thetemperatures at which the hives died were recorded. The mean temperature was 37 degrees F with standard deviation 4 degrees F. Assuming that the killing temperature level is normally distributed, test the claim that the mean killing temperature is different from 36 degrees F. Use a 1% level of significance.
