Question:

Stats again.?

A textile fiber manufacturer is investigating a new drapery yarn, which has a standard deviation of 0.3 kgThe company wishes to test the hypothesis H(0): mu 14 against H(1) mu lt; 14, using a random sample of five specimens.a) Find beta (type 2 error) for the case where the true mean elongation force is 13.5 kg and we assume that type one error 0.05.b) What is the power of this test (from a)now assume n 5c) find the boundary of the critical region if the type 1 error probability is specified to be 0.01d) Fine beta (type 2 error) for the case when the true mean elongation force is 13.5 kge) what is the power of the test now?I keep reading the chapterand i think I get itthen I check my answers and it just rejects them every time gt;.gt; I'm so damn lost

Answer:

Seal them, every unsealed hole is a potential air and/or water infiltration pointDoes not make sense to me to blow in insulation then leave holes for the cold air to enter.
It really isn't necessary to seal the holesThe siding will keep water out and the cellulose should be quite firmly packed, minimizing the opportunity for air infiltrationIf you are worried, though, you could probably cover the holes with a good quality duct tape - don't get the cheap crap!! Leaving them for ventilation is a good theory, but in reality, it won't make much difference.
wow! I took that stuff 12 years agoHeck if I remember how to do itGood luck!
