A local manufacturer of wooden furniture orders timber from nearby mills, to make their various products such as tables, chairs, and bedframes. One of the woodworkers there expresses their dissatisfaction with the quality of the timber supplied by the mills, and states that in their opinion, more than half of their timber pieces of a certain size range contain unworkable flaws.
a) Test this claim, at LOC = 90%, against a subsequent random sample of 50 timber pieces in this size range, of which 24 pieces contain unworkable flaws. Use the critical-value method.
b) Use the p-value method to determine if the result from Part (a) would be different for any other common LOC.
