Problem 3
Ten measurements of an impurity concentration in a process stream have been
recorded. The sample mean is 87ppm and the sample standard deviation is ±13 ppm.
Consider the null hypothesis that the impurity concentration has a true mean μo.
Part A: Desired Probability that the sample mean will satisfy the null hypothesis:
P = 0.4
Part B: Using the chart below, determine the4 highest value of the true mean that will lead
to the null hypothesis being accepted with the probability assigned in Part A

Problem 2
A chemical reactor system has been designed to perform optimally when operated
at 150°C. The hypothesis test that will be used for evaluating the operating temperature will
rely on 10 successive temperature measurements and will assign a 95% confidence
interval for the result. The reactor system is judged to have a standard deviation of ±3°C.
Part A: Actual operating temperature of the process T[°C] = 152.90
Part B: What is the probability that the hypothesis test for operating at 150°C described
above will give a false acceptance (i.e., a type II error)?

- Suppose that a coin is tossed twice so that the sample space is S= {HH, HT, TH, TT}. Let X represent the number of heads that can come up. With each sample point we can associate a number for X as shown in Table. Thus, for example, in the case of HH (i.e., 2 heads), X =2 while for TH (1 head), X = 1.

Refer to the excel data in the image provided to answer Part B. SoftBus Company sells PC equipment and customized software to small companies to help them manage their day-to-day business activities. Although SoftBus spends time with all customers to understand their needs, the customers are eventually on their own to use the equipment and software intelligently. To understand its customers better, SoftBus recently sent questionnaires to a large number of prospective customers. Key personnel—those who would be using the software—were asked to fill out the questionnaire. SoftBus received 82 usable responses, as shown in the file. You can assume that these employees represent a random sample of all of SoftBus's prospective customers. SoftBus believes it can afford to spend much less time with customers who own PCs and score at least 4 on PC Knowledge. Let's call these the "PC-savvy" customers. On the other hand, SoftBus believes it…arrow_forwardSuppose you are gambling on a roulette wheel. Each time the wheel is spun, the result is one of the outcomes 0, 1, and so on through 36. Of these outcomes, 18 are red, 18 are black, and 1 is green. On each spin you bet $5 that a red outcome will occur and $1 that the green outcome will occur. If red occurs, you win a net $4. (You win $10 from red and nothing from green.) If green occurs, you win a net $24. (You win $30 from green and nothing from red.) If black occurs, you lose everything you bet for a loss of $6. a. Use simulation to generate 1,000 plays from this strategy. Each play should indicate the net amount won or lost. Then, based on these outcomes, calculate a 95% confidence interval for the total net amount won or lost from 1,000 plays of the game.
