14) In tests of a computer component, it is found that the mean time between failures is 520
hours. A modification is made which is supposed to increase the time between failures.
Tests on a random sample of 10 modified components resulted in the following times (in
hours) between failures.
518 548 561 523 536
499 538 557 528 563
At the 0.05 significance level, test the claim that for the modified components, the mean
time between failures is greater than 520 hours. Use the P-value method of testing
hypothes

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use either the traditional method or P-value method as indicated. Identify the null and alternative hypotheses, test statistic, critical value(s) or P-value (or range of P-values) as appropriate, and state the final conclusion that addresses the original claim. 36) In tests of a computer component, it is found that the mean time between failures is 520 hours.

The mean time between failures (in hours) for a Telektronic Company radio used in light aircraft is 420h. After 15 new radios were modified in an attempt to improve reliability, tests were conducted to measure the times between failures. For the 15 new radios, the average time between failures was 434.73h and the standard deviation was 18.01h. Compute a 95% confidence interval. Does it appear that the modification improved the reliability?

The mean time between failures (in hours) for a Telektronic Company radio used in light aircraft is 420. After 15 new radios were modified in an attempt to improve reliability, tests were conducted to measure the times between failures. The mean time for 15 new radios is 442.2 and the standard deviation (S) is 44.0. Test the claim that the modified radios have a mean greater than 420.0 using a significance level 0.025.

The mean time between failures for a type of radio used in light aircraft is 420 hours. Fifteen of this type of radio were modified to improve reliability, and test data showed a mean of 442.2 hours with a standard deviation of 44.0 hours. a. Use a 5% level of significance to test the claim that the mean reliability has improved. b. If you use a 1% level of significance, does this change your conclusion? Explain

Your firm works in construction and buys ASTM A325M8S bolts in very large numbers. You are interested in purchasing bolts from different suppliers and have obtained and tested samples of 200 bolts from three suppliers: Allnutt, Boltzman, Coachers.You have tested these in your new bolt testing machine, purchased after you had discovered your old bolt testing machine was performing erratically. (For the purposes of this question, you are safe to assume that the new machine works perfectly and that its...
