What would be the total fire insurance premium for Best Hardware if their $655,000 building belongs in structural classification B? The contents are worth $830,250 and they received an area rating of 4. The rates per $100 are found in Table 19-4. (Round your answer to the nearest cent.)
The quality control engineer at Palmer Industries is interested in estimating the tensile strength of steel wire based on its outside diameter and the amount of molybdenum in the steel. As an experiment, she selected 25 pieces of wire, measured the outside diameters, and determined the molybdenum content. Then she measured the tensile strength of each piece. The results of the first four are recorded in the table. Tensile Strength Outside Diameter Amount of Molybdenum Place (PSI ) Y (mm) X1 (Units) X2 A 11 0.3 6 B 9 0.2 5 C 16 0.4 8 D 12 0.3 7 Using a statistical software package, the QC engineer determined the multiple regression equation to be Y’=-0.5+20X1+1X2. a) Based on the equation, what is the estimated tensile strength of a steel wire having an outside diameter of .35 mm and 6.4 units of molybdenum? b) Interpret the value of b1 in the equation.

The highway department wants to estimate the proportion of vehicles on a Highway at KM 25 between midnight and 5:00 A.M. The head of the department wants to see how many 18-wheel tractor trailers pass on the road. These estimates will be used to determine highway repairs and construction considerations and in highway patrol planning. The department chief asked investigators to calculate estimates of vehicles at different locations on inter-island roads over the past 7 days. From 3,481 vehicles counted there are 927 are 18-wheel drive. However, out of the total 927, there were 51 vehicles that had accidents so that the sample was calculated based on the results of a reduction in the number of accidents. Specify an approximate point for the proportion of vehicles performingtravel on KM 25 during this time period which is an 18-wheeled vehicle!(Assume the confidence level is 99%). What are the benefits of estimating value estimates in this case (analysis of the answers you have obtained)?
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. The temperatures of eight different plastic spheres.
The average concentration of ozone in unpolluted tropospheric air is 50 ppbV (that is, fifty molecules of ozone per billion molecules of air). You are trying to determine whether pollution has elevated average tropospheric ozone concentrations above the 50 ppbV “background” level at a particular location. You take five concentration measurements and obtain values of 30, 74, 48, 90, and 85 ppb. Based on other studies of ozone in the troposphere, you assume that these measurements were obtained from a normal distribution. Note in this instance, the null hypothesis should be set up similar to the way I set things up in the lecture for the DeSpoille and Pillage example. (a) What are the mean, standard deviation, and standard error of the mean of measured ozone concentrations? (b) In testing whether the average concentration is elevated above the “background”, what should be yournull hypothesis? Should you use a one- or two-tailed test? (c) Can you reject the null hypothesis at a…

What is the average NO3- concentration at the upslope site (3 decimal places)? What is the average NO3- concentration at the downslope site ( 3 decimal places)? Given the EPA drinking water quality standard is 10 mg/L of nitrate, is the upslope site safe to drink based only on nitrate content? (Enter yes or no) Is the downslope site safe to drink, based only on NO3- concentration? (Enter yes or no) Assuming the two sites are hydrologically well connected, the transit time between the two sites is fast, and the two sites cannot be treated as independent samples, what kind of t-test should be performed to show that the upslope site is greater than the downslope site? Enter the letter of your answer choice in the answer blank A. one-tailed unpaired t-testB. two-tailed unpaired t-testC. one-tailed paired t-testD. two-tailed paired t-test What is the calculated t statistic, rounded to 4 decimal places? Is the calculated t statistic greater or less than the critical t value reported by…
