Flexural strength design check of sections of a typical internal portal frame:
The load cases which you are expected to analyse for portal frame in this exercise, and from which the design bending moments and the coincident axial forces required for this section should be derived, are discussed in the ‘Supplementary Notes’. The moment capacities Msx and Mbx and the axial capacities Ns, Ncx and Ncy may be determined using the tables in the AISC ‘Design Capacity Tables for Structural Steel’ publication.
Rafters:
Check the flexural strength of the rafters in a typical internal
portal frame, in the general vicinity of the ridge. Again, check
for the two cases of maximum sagging B.M. at or near the ridge and
maximum hogging B.M. at or near the ridge, and allow for the
coincident axial force. Again, note that:
The purlins in the roof are at 1250mm centres, generally.
Assume there is fly bracing at the ridge and then at 4 spaces
from the ridge (obtain value depending on frame geometry).
For the rafters assume Grade 300 steel.

A study was conducted to investigate the hypothesis that living within 100 meters of a large highway increased the risk of childhood respiratory illness. The investigators recruited 200 children ages 6 to 10 years old living near highways and another 200 children of similar age, gender and ethnicity living more than 100 meters from highways. They followed the children for 3 months and asked the parents to record in a daily diary any symptoms of respiratory illness. At the end of the 3 months, 36 of the 200 “exposed” children (living near a highway) had developed at least one respiratory illness, while 17 of the 200 living further away had developed respiratory illness. a. What kind of study was this? b. What measure of disease frequency can be calculated? Calculate it for each group and interpret the results. c. What measure of association can be calculated? Calculate it and interpret the results.

An article contained the following observations on degree of polymerization for paper specimens for which viscosity times concentration fell in a certain middle range:
| 415 | 421 | 422 | 422 | 425 | 427 | 430 | 435 | 436 |
| 439 | 446 | 446 | 448 | 453 | 457 | 462 | 464 |
(a) Construct a boxplot of the data.
Comment on any interesting features. (Select all that apply.)
The data appears to be centered near 428.There are no outliers.The data appears to be centered near 438.There is one outlier.There is little or no skew.The data is strongly skewed.
(b) Is it plausible that the given sample observations were
selected from a normal distribution?
YesNo
(c) Calculate a two-sided 95% confidence interval for true average
degree of polymerization. (Round your answers to two decimal
places.)
,
Does the interval suggest that 443 is a plausible value for true
average degree of polymerization?
YesNo
Does the interval suggest that 450 is a plausible value?
YesNo

An important application of regression analysis in accounting is in the estimation of cost. By collecting data on volume and cost and using the least squares method to develop an estimated regression equation relating volume and cost, an accountant can estimate the cost associated with a particular manufacturing volume. Consider the following sample of production volumes and total cost data for a manufacturing operation.
| Production Volume (units) | Total Cost ($) |
| 400 | 4,700 |
| 450 | 5,700 |
| 550 | 6,100 |
| 600 | 6,600 |
| 700 | 7,100 |
| 750 | 7,700 |

Smart Stream Inc. uses the total cost method of applying the cost-plus approach to product pricing. The costs of producing and selling 7,500 units of cell phones are as follows:
| Variable costs: | Fixed costs: | |||
| Direct materials | $ 85 | per unit | Factory overhead | $321,900 |
| Direct labor | 39 | Selling and administrative expenses | 113,100 | |
| Factory overhead | 26 | |||
| Selling and administrative expenses | 20 | |||
| Total variable cost per unit | $170 | per unit | ||
Smart Stream desires a profit equal to a 14% return on invested assets of $952,710.
a. Determine the total cost and the total cost amount per unit for the production and sale of 7,500 units of cellular phones. Round the cost per unit to two decimal places.
| Total cost | $ |
| Total cost amount per unit | $ |
b. Determine the total cost markup percentage
(rounded to two decimal places) for cellular phones.
%
c. Determine the selling price of cellular
phones. Round to the nearest cent.
