  1. Fifty specimens of a new chip were tested for speed in a certain application, along with 50 specimens of chips with the old design. The average speed, in MHz, for the new chips was 486.6, and the standard deviation was 18.4. The average speed for the old chips was 451.6 and the standard deviation was 13.3. Test the hypothesis that the mean speed for the new chips is greater than that of the old chips.
  1. State the null and alternative hypothesis.

  1. Compute the test statistics.

  1. Compute the P-value.

  1. State a conclusion

A sample of 60 even older chips had an average speed of 391.2 MHz with a standard deviation of 17.2 MHz. Someone claims that the new chips average more than 100 MHz faster than these very old chips. Do the data provide convincing evidence for this claim? State the appropriate null and alternative hypotheses, use Minitab to compute the p-value of the test, then state your conclusion. Use a significance level of α=.05. Please solve using minitab and show the...

To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen is then measured, yielding a sample average penetration of x = 52.3 and a sample standard deviation of s = 4.2. The conduits were manufactured with the specification that true average penetration be at most 50 mils. They will be used unless it can be demonstrated conclusively that...

To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen is then measured, yielding a sample average penetration of x = 53.2 and a sample standard deviation of s = 4.2. The conduits were manufactured with the specification that true average penetration be at most 50 mils. They will be used unless it can be demonstrated conclusively that...

A researcher claims that the average wind speed in a certain city is 8 miles per hour. A sample of 32 days has an average wind speed of 8.2 miles per hour. The population standard deviation is 0.6 mile per hour. At a=0.05, do these data determine whether the average wind speed in a certain city is different from 8 miles per hour? a) state the hypothesis b) calculate the test statistic

A researcher claims that the average wind speed in a certain city is 6 miles per hour. A sample of 33 days has an average wind speed of 6.5 miles per hour. The standard deviation of the population is 1 mile per hour. At 0.07 significance level, is there enough evidence to reject the claim? Determine the null hypothesis, the p-value, and state your conclusion.
