Aconcrete mixture for a proposed building work is to be designed. A characteristic compressive strength of 25 MPa with 5% defective rate is specified for 28 days. The standard deviation may be taken based on a compressive strength results on specimens less than 20. A slump of 40 mm is required and the maximum w/c ration and the minimum cement content allowed are 0.7 and 200 kg/m3, respectively. The fine aggregate is uncrushed and the percentage passing sieve 600 Micro...

Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows. Can you conclude that the mean strength after three days is greater than the mean strength after six days? Let μ1 represent the mean strength after three days and =μd−μ1μ2. Use the =α0.01 level and the P-value method with the TI-84 Plus calculator. Block 1. 2 3. 4. 5...

The cooling system in a nuclear submarine requires the specifications that the average weld strength must meet or exceed 150 psi for proper coolant circulation. A random sample of 36 welds results in x ̅=157 psi and s=15 psi. A design engineer wants to test the specifications based on the sample information at 5% level of significance. Complete the hypothesis test by answering the following questions. State the hypotheses. Calculate the test statistic. What is/are the critical value(s)? What is...

5. A manufacturer of college textbooks is interested in estimating the strength of the bindings produced by a particular binding machine. Strength can be measured by recording the force required to pull the pages from the binding. If this force is measured in pounds, how many books should be tested in order to estimate with 95% confidence to within 0.1 lb the average force required to break the binding? Assume that  is known to be .8 lb. 6. We...

For exercise prescription: Ms. Case Study-WM is a 48-year-old woman who works 5 days per week as a bank executive. She previously walked up the stairs to her third floor office but has started to use the elevator because, in the past month, she has experienced shortness of breath when walking up the stairs. The patient was physically active throughout college as a club lacrosse player but has not exercised regularly since she gave birth to her children who are...
