Claim: The standard deviation of pulse rates of adult males is more than 12 bpm, For a random sample of 149 adult males, the pulse rates have a standard deviation of 13.1 bpm. Complete parls(a) and ([1) below. a. Express he original claim in symbolic form. Y I bpm (Type an integer or a decimal. Do not round.) Claim: Most adults would erase all of their personal information online if the}.r could. A software rm survey of 494 randomly selected adults showed that 55% of them would erase all of their personal information online if the):r could. Find the value of the test statistic. The value of the test statistic is . (Round to two decimal places as needed.) Claim: The standard deviation of pulse rates of adult males is less than 10 bpm. For a random sample of 171 adult males. the pulse rates have a standard deviation of 9.5 bpm. Find the value of the test statistic. The value of the test statistic is . (Round to two decimal places as needed.) The test statistic of z = 1.50 is obtained when testing the claim that p > 0.7. 3.

Use either the Prvalue method or the traditional method of testing hypotheses Company A uses a new production method to manufacture aircraft altimeters. A simple random sample of new altimeters resulted in errors listed below. Use a 0.05 level of signicance to test the claim that the new production method has errors with a standard deviation greater than 32.2 ft, which was the standard deviation for the old production method. If it appears that the standard deviation is greater, does the new production method appear to be better or worse than the old method?
