If the standard deviation of a hole-diameter exceeds 0.01 millimeters, there is an unacceptably high probability that the rivet will not fit. Suppose that n = 15 and s = 0.008 millimeters
1. Is there a strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters? Use? = 0.01. State any necessary assumptions about the underlying distribution of the data. Find the P-value for this test
2. Suppose that the actual standard deviation of hole diameter exceeds the hypothesized value by 50%. What is the probability that this difference will be detected by the test described in part (a)?
3. If s is really as large as 0.0125 millimeters, what sample size will be required to detect this with power of at least 0.8?
Given a prime number, use Generating functions to find the prime number that immediately follows it. For example, if I give a 5, then there will be F(2,3,5) = 7 ; if I give a 11, there will be F(2,3,5,7,11) = 13 ....... (this is a function of all pri..
