Compute for its value from the given information. Show the process in solving. No need to find the critical value and sketch the curve.

1. Ho: =200 H: <200 the sample mean is 210 , size 40 and standard deviation 10. use =0.05.

2. The manufacturer owner claimed that their bottle of water has the capacity mean of beyond 300 ml with the standard deviation of 60 ml. To test the claim, a consumer gets a sample of 100 bottles of water and the sample mean of 308 ml. Use 0.10 level of significance to test the claim.
