To test the accuracy of the micrometer, the wire thickness was measured 60 times and an empirical standard deviation of 0.05 mm was obtained. Assuming that the distribution of measurement errors is normal, examine at the significance level 0.05 the hypothesis that the micrometer measures with an accuracy of 0.04 mm.
a) The test statistics with the relevant test is:
b) At the significance level of 0.05 WE REJECT / WE DO NOT REJECT H0

The absorbance of a 1 mg/ml sample of lysozyme was measured in a cuvette of thickness 1.00 cm and was found to be 3.19 at 240 nm and 2.58 at 280 nm. The molar absorption coefficients of tryptophan and tyrosine at 240 nm are 2.00 x 103 dm3 mol-1 cm-1 and 1.12 x 104 dm3 mol-1 cm-1, respectively, and at 280 nm they are 5.40 x 103 dm3 mol-1 cm-1 and 1.50 x 103 dm3 mol-1 cm-1, respectively.

A health research company was engaged to test the accuracy of COVID-19 test kits used in Queensland. A sample of 50 test kits was analysed to see whether they gave the correct test result. An interval estimate of 0.46 to 0.70 was found for the population proportion of test kits which gives the correct test result. What is the level of confidence used for this test? (Answer as a percentage to two decimal places. Do not include the % symbol).

We are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 98 percent reliable, this means that the test will yield an accurate positive result in 98% of the cases where the disease is actually present. Gestational diabetes affects 9 percent of the population in our patient’s age group, and that our test has a false positive rate of 12 percent. Use your knowledge of...

Choose the appropriate decision rule at the .10 level of significance. Reject H0 if z > 1.282 Reject H0 if z < 1.282 (a-2) Calculate the test statistic.

One Hypothesis test is an F test for the equality of the variances of travel Times and the second test is a T-test for the equality of the means of travel times in MINUTES.

One Hypothesis test is an F test for the equality of the variances of travel Times and the second test is a T-test for the equality of the means of travel times in MINUTES. The F test must be performed first in order to select either Case1 or Case 2 for the T-test as listed in chapter 5. Then perform the Required T-test (either case 1 or 2 depending on your findings of the F-test). Also in the Conclusion...
