This policy ensures that all students in grades one to nine are physically active for at least thirty minutes each day through activities organized by the school (Alberta, 2020). Being active is being healthy. As was mentioned in the Dr. Christine Kennedy’s article schools have the potential to help children develop lifelong, healthy eating patterns and encourage physical activity; research supports school-based interventions to increase physical activity and decrease obesity (Kennedy, 2010).
Giving the kids an opportunity to have an active form of break, allows them to get the proper physical attention to the young body. This increase the overall mental and physical health. Kids between ages of 6 to 14 are in the most important period of they life, when the body and bones are forming. Therefore, this initiative that came to Alberta schools in 2005 was widely accepted and implemented by all the schools across the province.
come up with a discussion question. Something that a rival or someone who is against this policy would say.

) Jaeco Corporation asks you to review its December 31, 2020 inventory values and prepare the adjustments that are needed to the books. The following information is given to you: • 1. Jaeco uses the periodic method of recording inventory. A physical count reveals $234,890 of inventory on hand at December 31, 2020, although the books have not yet been adjusted to reflect the ending inventory. • 2. Not included in the physical count of inventory is $10,420 of merchandise purchased on December 15 from Shamsi. This merchandise was shipped f.o.b. shipping point on December 29 and arrived in January. The invoice arrived and was recorded on December 31. • 3. Included in inventory is merchandise sold to Sage on December 30, f.o.b. destination. This merchandise was shipped after it was counted. The invoice was prepared and recorded as a sale on account for $12,800 on December 31. The merchandise cost $7,350, and Sage received it on January 3. • 4. Included in the count of inventory was merchandise received from Dutton on December 31 with an invoice price of $15,630. The merchandise was shipped f.o.b. destination. The invoice, which has not yet arrived, has not been recorded. • 5. Not included in inventory is $8,540 of merchandise purchased from Growler Industries. This merchandise was received on December 31, after the inventory had been counted. The invoice was received and recorded on December 30. • 6. Included in inventory was $10,438 of inventory held by Jaeco on consignment from Jackel Industries. • 7. Included in inventory was merchandise sold to Kemp, f.o.b. shipping point. This merchandise was shipped after it was counted, on December 31. The invoice was prepared and recorded as a sale for $18,900 on December 31. The cost of this merchandise was $11,520, and Kemp received the merchandise on January 5. • 8. Excluded from inventory was a carton labelled “Please accept for credit.” This carton contained merchandise costing $1,500, which had been sold to a customer for $2,600. No entry had been made to the books to record the return, but none of the returned merchandise seemed damaged. • 9. Jaeco sold $12,500 of inventory to Simply Corp. for $21,000 on account on December 15, 2020. These items were shipped f.o.b. shipping point. The terms of sale indicate that Simply Corp. will be permitted to return an unlimited amount until May 15, 2021. Jaeco has never provided unlimited returns in the past and is not able to estimate the amount of any potential returns that Simply may make. Instructions a. Determine the proper inventory balance for Jaeco Corporation at December 31, 2020. b. Prepare any adjusting/correcting entries that are needed at December 31, 2020. Assume the books have not been closed and that Jaeco follows IFRS. c. Assume instead that Jaeco follows ASPE. Prepare any adjusting/correcting entries at December 31, 2020, that are needed.

The remaining questions in this workbook assignment are based on the following scenario.
Information was collected from a reputable internet site for an
investigation into the fuel economy of various makes of car and
whether these varied over time. Data was collected for fifteen
different models of vehicle from twelve different manufacturers.
After collection, the observed vehicle models were classified as
sedan, sports or 4WD.
The data for sedans is provided in the file sedan_economy.csv, also
available in the same folder as this assignment. The variables in
this file are:
decade: the decade in which the car was produced ((1991-2000,
2001-2010, 2011-present);
economy: fuel economy (L/100km);
cylinders: the number of cylinders in the engine;
capacity: the engine capacity (L);
fuel: the fuel type (petrol or diesel);
transmission: the transmission of the car (manual or
automatic).

The sample averages of fuel economy for manual and automatic
sedans in this sample are 7.854 L/100km and 9.09 L/100km,
respectively. Based on this, one of the investigators has suggested
that it may be possible to predict the transmission type of a sedan
from its fuel economy, using a formal statistical analysis.
(a) Using R, create a new variable isauto that takes the value 1 if
the transmission type is automatic, or a 0 if the transmission type
is manual. You should show the command you used to do this.
(b) You should then fit an appropriate statistical model that
describes the probability of a randomly chosen car having an
utomatic transmission, where the fuel economy is a predictor. You
should ensure you show the command you used to do this, and provide
the coefficient/summary table.
(c) Is fuel economy a significant predictor of the probability of a
randomly chosen car having an automatic transmission?
(d) Your friend is looking to purchase a sedan with a manual
transmission from an online seller, who has not included the
transmission type of the car in the advertisement description.
However, the seller has stated in the advert that his 60L tank
gives a range of 730km. Whether or not you found fuel economy to be
a significant predictor in (d), calculate the average fuel economy
and hence determine the model estimate of the probability of the
car having a manual transmission.

A firm produces a single output using two variable inputs (denoted ?1 and ?2). The firmproduction function is given by ? = Φ(?1, ?2) = (?1?2) ^0.5. The firm can employ as much of either input it desires by incurring constant (and respectively denoted) per-unit input costs of ?1 and ?2. Assume throughout that all prices and quantities are positive and infinitely divisible. Finally, let ?0 denote the “target” level of output that the firm envisions producing when deciding how much of the inputs to employ.
(a) Show that the firm’s production technology displays a diminishing (physical) marginal product with respect to either input.
(b) Write down the firm’s cost minimization problem and solve for the firm’s total cost function, ??(?1, ?2, ?0). Show that the total cost function is homogeneous of degree one in input prices (i.e., ??(??1, ??2, ?0) = ? × ??(?1, ?2, ?0) for ? > 0). Provide an interpretation of this result.
(c) Show that the firm’s average total cost and marginal cost functions are equal and constants (i.e., do not depend on the level of output produced by the firm). What does this imply about the firm’s production technology?

Problem VI A-B: Apple used to produce two different versions of the Iphone, Iphone 5s and Iphone 5c. Assume the cost of production is zero. There are two types of consumers on the market, knowledgeable consumers and kids. Knowledgeable consumers value the Iphone 5s at $220 for its superior technology and the Iphone 5c at only $120. Kids don’t know that much about technology and they like colors a lot so their valuations are $110 for the Iphone 5s and $100 for the Iphone 5c. Apple is designing a pricing strategy to sell the Iphone.
a) Apple is considering a price discrimination strategy to sell the Iphone 5s to knowledgeable customers and the Iphone 5c to kids for two different prices. Write down the individual rationality and incentive compatibility constraints for the two types of customers. Find the optimal prices.
b) Assume there are N total consumers and the proportion of knowledgeable consumers is ?. That means there are ?N knowledgable consumers and (1 ? ?)N kids on the market. Write the profit function of Apple if the price discrimination mechanism is put into action.

The value of a college degree is greater than it has been in nearly half a century, a least when compared to the prospect of not getting a degree (www.pewresearch.org, January 28, 2014). Due to this fact, more and more people are obtaining college degrees, despite the soaring costs. The accompanying table shows the proportions of college degrees awarded in 2010 by colleges and universities, categorized by a graduate's race and ethnicity.
The race and ethnicity of 500 recent graduates are recorded and shown in the last column of the table.
| Race/Ethnicity | 2010 Proportions | Recent Numbers |
| White | 0.73 | 350 |
| Black | 0.10 | 50 |
| Hispanic | 0.09 | 60 |
| Asian | 0.08 | 40 |
At the 5% significance level, test if the proportions have
changed since 2010.
