According to the scientific method, a scientist isn't supposed to start out with preconceived notions and then grasp for any evidence that might back up his/her conclusions. Instead, if he/she has a hypothesis, he/she is supposed to test it. If the tests confirm that there's something to the hypothesis, the hypothesis becomes either a theory or a law.

Doesn't it seem to you that the Intelligent Design proponents have started off with a Creationist world view, and they have been grasping for whatever evidence might back up their claims?

A manufacturer has developed a new kind of mobile-phone battery that he claims has a mean lifetime of 8.0 hours with a standard deviation of 0.5 hour. To test the null hypothesis that µ =8.0 hours versus the alternatives that µ <8.0 hours, a random sample of 50 batteries will be tested. The critical region is defined to be x < 7.9, ie. Reject the null hypothesis if sample mean is found to be less than 7.9 hours. Find the probabilities of committing (i) a type I error; (ii) a type II error when µ=7 hours

A rectangular tank has a horizontal base. Water is flowing into the tank at a constant rate, and flows out at a rate which is proportional to the depth of water in the tank. At time t seconds the depth of water in the tank is x metres. If the depth is 0.5m, it remains at this constant value. Show that

dx/dt = - K(2x - 1)
