Test the hypothesis that the average amount o a a particular substance in a container is µ0 = 10.1 liters, if the recorded contents of a random sample of 8 containers are 10.1, 9.9, 9.8, 10.4, 10.2, 10.6, 9.7, 9.5. Use a 0.05 level of significance and assume that the distribution of contents is normal. Perform the test against the alternative hypotheses (a) µ 6= µ0, (b) µ > µ0 and (c) µ < µ0. (Hint: Use the t–distribution)

In using statistical test of hypothesis in general and in business in particular, business practitioners face two types of errors: type I and type II error. Discuss each type of error in detail. In your opinion which type has more severe consequences in business? Support your opinion by providing an example. Also, discuss what is P-Value and its connection to type I error.

1) A radioactive substance decays at a rate proportional to the amount of the substance at present time. Initially 200 grams of a the substance was present and remain 80% of the initial amount after 2 hours. A.) Determine the amount of the substance remaining after 10 hours (counted in grams) B.) Determine the time that 60% of the initial amount of the substance has decayed (counted in hours)

The average time it takes to complete a particular sociology test is 86.5 minutes. In a recent study of 26 individuals that took it a particular test the average amount of time to complete the sociology test was 83.4 minutes. The sample standard deviation was 8.7 minutes. At the 0.10 level of significance can it be concluded that the average amount of time it takes to complete the particular sociology test is less than 86.5 minutes.

1. Test the hypothesis that the average life of a bulb is 1600 hr. against the alternative that it is 1570 hr. For engineering reasons, only 16 bulbs could be tested obtaining an average of 1590 hr. with a standard deviation of 30 hr. Use a 99% confidence level. Calculate the value of β. 2. An automatic box filling machine has a variability of 0.05 lb. A new automatic machine will be compared with the previous one, and for this,...
