How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that 45 tissues is the average number of tissues used during a cold. Suppose a random sample of 36 Kleenex users yielded the following data on the number of tissues used during a cold: = 40.7, s = 15. Researchers want to conduct a test to determine if the number of tissues used during a cold is less than 45. In the context of this questions, which of the following interpretations of Type I Error is correct?

1. We mistakenly conclude the average number of tissues used during a cold is not different from 45 when in fact it is.
2. We mistakenly conclude the average number of tissues used during a cold is not greater than 45 when in fact it is.
3. We mistakenly conclude the average number of tissues used during a cold is greater than 45 when in fact it is not.
4. We mistakenly conclude the average number of tissues used during a cold is not less than 45 when in fact it is.
5. We mistakenly conclude the average number of tissues used during a cold is less than 45 when in fact it is not.
6. We mistakenly conclude the average number of tissues used during a cold is less than 45 when in fact it is.
