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 significance 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...
Question Help Test the given claim. Assume that a simple random sample is selected from a normally distributed population. Use either the P-value 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 significance to test the claim that the new production method has errors with a standard deviation greater than 32.2 ft, which...

Answer option
Since the test statistic is (lessthan than. between.
greater than. equal to) the critical value {s},
(reject. fail to reject) Ho. There is
(insufficient. sufficient) evidence to support the
claim that the new production method .
The variation appears to be (about the same. Greater.
less) than the past, so the new method appears to be
(similar. Better. worse) because there will be
( the same number of. more. fewer) altimeters
that
Have rrors. Therefore, the company...
A.
Compute the test statistic x2=_____ (Round to three
decimal places)
Find the P-value=______ (Round to three decimal places)
Reject/Fail To reject _____ H0. There is/is not_____ sufficient
evidence to warrant rejection of the claim that pulse rates of
women have a standard deviation equal to 10 beats per minute.
B.
Find the test statistic= x2=_____ (Round to three decimal
places)
Find the p-value of test statistic=_______ (Round to three
decimal places)
(1) _________H0. There(2)__________sufficient evidence to
conclude that the...
Use the traditional method to test the given hypothesis. Assume that the population is normally distributed and that the sample has been randomly selected. A manufacturer uses a new production method to produce steel rods. A random sample of 37 steel rods resulted in lengths with a mean 6 and standard deviation of 4.7 cm. At the 0.10 significance level, test the claim that the new production method has mean 5.5 cm, which was the mean for the old method.
1) Use either the critical value or p-value method for testing hypotheses. 2) Identify the null and alternative hypotheses, test statistic, P-value (or range of P-values), and critical value(s). 3) State your final conclusion that addresses the original claim. Include a confidence interval as well and restate this in your original conclusion. A credit card company wondered whether giving frequent flier miles for every purchase would increase card usage. The population mean had been $2500 per year. A simple random...
Test the given claim. Use the P-value method or the traditional method as indicated. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s) or P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. -------------------- QUESTION: A simple random sample of 15-year old boys from one city is obtained and their weights (in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with...
Test the given claim. Use the P-value method or the traditional method as indicated. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s) or P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below. Use a...
