The strengths of individual bars made by a certainmanufacturing process are approximately normallydistributed with mean 28.4 and standard deviation 2.95(in appropriate units). To ensure safety, a customerrequires at least 95% of the bars to be stronger than24.0.a.) Do the bars meet specifications? (That is, are thereat least 95% of bars exceeding 24.0?)b.) By improved manufacturing techniques themanufacturer can make the bars more uniform(that is, decrease the standard deviation). Whatvalue of the standard deviation will just meet thecustomer's specification if the mean stays thesame?

The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 3.00 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 43 randomly selected calls. The mean wait time was calculated to be 3.28 minutes. Assuming the population standard deviation is 0.87 minutes, is there sufficient evidence to say that the mean wait time for customers is longer than 3.003.00 minutes with a 95% level of confidence?

The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 4.00 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 34 randomly selected calls. The mean wait time was calculated to be 4.61 minutes. Assuming the population standard deviation is 1.93 minutes, is there sufficient evidence to say that the mean wait time for customers is longer than 4.00 minutes with a 95% level of confidence? Step 3 of 3 : Draw a conclusion and interpret the decision. Answer A.We reject the null hypothesis and conclude that there is sufficient evidence at a 95% level of confidence to support the claim that the mean wait time is longer than 4.00 minutes.B. We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 95% level of confidence to support the claim that the mean wait time is longer than 4.00 minutes.

The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 3.50 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 41 randomly selected calls. The mean wait time was calculated to be 3.94 minutes.

A comparison is made between two bus lines to determine if arrival times of their regular buses from Denver to Durango are off schedule by the same amount of time. For 51 randomly selected runs, bus line A was observed to be off schedule an average time of 53 minutes, with standard deviation 17 minutes. For 60 randomly selected runs, bus line B was observed to be off schedule an average of 62 minutes, with standard deviation 11 minutes. Do the data indicate a significant difference in average off-schedule times? Use a 5% level of significance.What are we testing in this problem? single mean or paired difference or difference of means or difference of proportions or a ingle proportion What is the level of significance?State the null and alternate hypotheses.

The board of a major credit card company requires that the mean wait time for customers for service calls isat most 3.00 minutes. To make sure that the mean wait time is not exceeding the requirement, anassignment manager tracks the wait times of 45 randomly selected calls. The mean wait time wascalculated to be 3.4 minutes. Assuming the population standard deviation is 1.45 minutes, is there sufficientevidence to say that the mean wait time is longer than 3.00 minutes with a 98% level of confidence?
Suppose the Production Operation Manager at the canning plant for evaporated milk is faced with a problem. Because of the designed machine, it generated a standard deviation of 7 ml in the filling of evaporated milk, but the average ml per fill can be adjusted. Under fear of revocation of license to operate and penalty charges by the Department of Trade and Industry (DTI), the management of the company has ordered the manager to set the filling machine so that there is a maximum 10% chance of a 370 ml can content less than 356 ml. What should the average be? Solution: Step 1: Draw a figure and represent the area. Step 2: Find the z value. Step 3: Solution to find the average.
