You work for a company that produces electronics with integrated circuits. One of your products is called a "shift register." This product is designed to automatically shut down if its operating temperature exceeds 175 degrees Celsius. The manufacturing process has been designed to have a standard deviation of $\sigma = 0.4$ degrees Celsius. You test a random sample of 19 shift registers, and you record the following shut-down temperatures. Construct a 80% confidence interval for the overall mean shutdown-temperature.| 175.18 | 175.45 | 174.3 | 174.98 | 175.58 | 174.95 ||--------|--------|--------|--------|--------|--------|| 174.2 | 175.54 | 174.89 | 174.41 | 174.82 | 175.3 || 175.27 | 175.1 | 174.65 | 175.03 | 175.71 | |*(Checksum: 3325.78)***a) Find the critical value and $\sigma_{\bar{x}}$.**Critical Value: $\_\_\_\_$$\sigma_{\bar{x}}: \_\_\_\_$**b) Find the confidence interval:** $(\_\_\_\_, \_\_\_\_)$

The given sum is 3325.78 for 19 shifts and population standard deviation is 0.4.

QUESTION 6 ANZ Bank's Wealth Management Division conducted a survey of the value of the new business created over the last month in millions of dollars. From 23 responses, the mean and standard deviation were found to be $1.741 and $0.989 million respectively. Assuming the data were collected through a random sample and that the value of new business is approximately normally distributed, calculate a 95% confidence interval estimate of the average value of new business per month in millions of dollars. State only the upper bound correct to three decimal places.
Question 1. Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in the average amount of time individuals waste at the courthouse waiting to be called for service. The committee randomly surveyed 81 people. The sample average was 8 hours with a sample standard deviation of 4 hours. (a) Construct a 95% confidence interval for the population average time wasted and write the interpretation (Sketch the graph). (b) Which distribution you used for this problem? Explain your choice.
QUESTION 1 A recent study of over 1000 parents on cyberbullying showed that a 95% confidence interval of proportion of kids who faced bullying in social media sites and apps is (0.1200, 0.1433). Find the sample proportion of kids who faced bullying in social media sites and apps. Round your answer to four decimal places. QUESTION 2 The amount of time a bank teller spends with each customer has a population mean of 5 minutes and a standard deviation of 1.5 minute.

QUESTION 3 The daily electrical energy consumption (in Watts) during July for a random sample of households was recorded. The mean was 3399 W and the standard deviation was 316 W. Assume the underlying distribution of the consumption is normal. Find the marging of error E of the 95% confidence interval for the mean daily electrical energy consumption during that month.…
Question 1 SlackBoard, a company producing a Learning Management System (LMS) would like to know whether they heed to run additional servers due to increased use of its LMS. SlackBoard knows that, historically, the average user spent about 75 minutes per day logged into their SlackBoard classes and that time spent logged in is approximately normally distributed. A recent random sample of 75 accounts resulted in an average tíme of 85 logged in.per day with a standard deviation of 64 minutes per day. Formulate and test a hypothesis to determine whether there is evidence to that there has been an increase in average individual use time per day. Conduct your test at a significance level of a = 0.01. Your hypotheses are: Ho: H = 75 Hạ: p > 75 Ho: p = 75 Hạ: P 0 What is the test statistic for this test? test statistic = (Report answer accurate to 2 decimal places.) %3D What is the p-value for this test? p-value = (Report answer accurate to 4 decimal places.)

QUESTION 1 A hardware store determined the current balances for a random sample of 100 customers with non-zero balances. The sample mean of the amount owed was $100.00 and the standard deviation was $25. Use the assumption that the sample standard deviation is equal to the population standard deviation. You are asked to find a confidence interval for the average amount owed by all customers with a non-zero balance. Which Minitab procedure would be most appropriate to use for this task?

Chapter 8. 5) A random sample of 43 Foreign Language movies made since 2000 had a mean length of 112.5 minutes, with a standard deviation of 12.6 minutes. (a) Construct a 95% confidence interval for the true mean length of all Foreign Language movies made since 2000 (b) As of November 2010, three Spider-Man movies have been released, and their mean length is 129 minutes. Someone claims that the mean length of Spider-Man movies is actually less than the mean length of all Foreign Language movies. Does the confidence interval contradict this claim? 6

Question 3 Assume the average teenager sends 250 text messages per day. You sample 28 local teenagers and find that they send 232 messages per day with a standard deviation (calculated with the correction) of 64 messages per day. What decision would you make based on these data? Fail to reject the null hypothesis; we cannot conclude that there is any difference between our sample and the nation. Fail to reject the null hypothesis; the local teenagers text more than the national average. Reject the null hypothesis; there is no evidence of a difference between our sample and the nation. Reject the null hypothesis; our sample sends significantly fewer text messages than the national average.
Question 6 Is smoking during pregnancy associated with premature births? To investigate this question, researchers selected a random sample of 118 pregnant women who were smokers. The average pregnancy length for this sample of smokers was 255 days. From a large body of research, it is known that length of human pregnancy has a standard deviation of 16 days. The researchers assume that smoking does not affect the variability in pregnancy length. Find the 95% confidence interval to estimate the length of pregnancy for women who smoke. (Note: The critical z-value to use, Ze, is: 1.960) ) Your answer should be rounded to 3 decimal places.
