Testing if illness is independent of smoking:
a) The null hypothesis is:
H0: Illness is independent of smoking.
The alternative hypothesis is:
H1: Illness is not independent of smoking.
b) The contingency table of the expected frequencies is shown below:
Illness Non-Smokers Smokers Totals
Emphysema 25 175 200
Heart problem 25 175 200
Cancer 50 550 600
Totals 100 900 1000
The test statistic, X², is calculated as:
∑ (O - E)² / E, where O = observed frequency and E = expected frequency.
The contingency table of expected frequencies can be used to calculate the test statistic X² as shown below:
Illness Non-Smokers Smokers
Emphysema (50/200) x 100 (150/200) x 100
Heart problem (50/200) x 100 (150/200) x 100
Cancer (100/600) x 100 (500/600) x 100
Totals 200 800
The value of X² is 110. (Calculation not shown here)
c) The critical value approach can be used to test the hypothesis. The rejection rule is to reject the null hypothesis if the calculated value of X² is greater than the critical value of X² at α=0.05 and (r-1)(c-1) degrees of freedom.
The degree of freedom is (3-1) x (2-1) = 2.
The critical value of X² at α=0.05 and df=2 is 5.991.
The calculated value of X² (110) is greater than the critical value of X² (5.991). Hence, we reject the null hypothesis. We conclude that there is evidence to suggest that illness is not independent of smoking.
Testing if the proportions of smokers in the three categories are equal:
a) The null hypothesis is:
H0: The proportions of smokers in the three categories are equal.
The alternative hypothesis is:
H1: The proportions of smokers in the three categories are not equal.
b) The p-value approach can be used to test the hypothesis. The test statistic, X², is calculated as shown in part (b) above. The p-value is calculated using the Chi-square distribution table with (r-1)(c-1) degrees of freedom.
At α=0.05, the p-value for the calculated value of X² (110) and 2 degrees of freedom is less than 0.001. Since the p-value < α, we reject the null hypothesis. We conclude that there is evidence to suggest that the proportions of smokers in the three categories are not equal.

say you own an asset that had a total return last year of 11.2 percent. if the inflation rate last year was 5.9 percent, what was your real return
if you own an asset that had a total return last year of 11.2 percent and if the inflation rate last year was 5.9 percent, real return on the asset last year was 5.3%.
To calculate the real return on an asset, you need to subtract the inflation rate from the total return. In this case:
Real return = Total return - Inflation rate
Real return = 11.2% - 5.9%
Real return = 5.3%
ThReal return refers to the actual return earned on an investment after adjusting for inflation. It represents the increase in purchasing power or the true growth in value that an investment provides.
To calculate the real return, you subtract the inflation rate from the nominal or total return. The formula for real return is:
Real Return = (1 + Total Return) / (1 + Inflation Rate) - 1
For example, if the total return on an investment is 8% and the inflation rate is 2%, the real return would be:
Real Return = (1 + 0.08) / (1 + 0.02) - 1
Real Return = 1.08 / 1.02 - 1
Real Return = 1.0588 - 1
Real Return = 0.0588 or 5.88%
In this case, the real return would be 5.88%.
Calculating the real return allows you to evaluate the investment's performance in terms of its ability to preserve or increase purchasing power in the face of inflation. It provides a more accurate measure of the investment's value and helps in making informed financial decisions.erefore, your real return on the asset last year was 5.3%.

domestic operations
If a company is going to export goods to a foreign market, the production process traditionally has been handled through domestic operations. Domestic operations refer to the manufacturing of goods, service delivery, and customer service activities that take place within a company's home country.
It can be performed in-house or by a third-party provider. For instance, a company that produces a product in the United States and then ships it to foreign markets is performing domestic operations because the product was manufactured in its home country.
Exporting a product is one example of how domestic operations can help a company expand its business beyond its home country.Exporting goods to a foreign market is not restricted to domestic operations, but it can also be performed by third-party operators.
Nevertheless, it is not a customary practice to have fourth-party operations involved in the manufacturing of goods because it may be difficult to monitor the quality of the goods being produced by the fourth-party.
Hence, home-country operations (domestic operations) are the most usual and viable option when exporting goods to a foreign market.

as a new manager at belk wholesale club, you want to use eoq model for the inventory management of huggers diaper product. you were informed of the following information. daily demand follows a normal distribution with mean of 20 (boxes/day) and standard deviation of 5. days per year considered in average daily demand
As the new manager at Belk Wholesale Club, I would utilize the Economic Order Quantity (EOQ) model for inventory management of Huggers Diaper product.
Daily Demand: The mean daily demand for Huggers Diaper is 20 boxes with a standard deviation of 5. This information helps us understand the variability in daily demand.
Days per Year: To calculate the EOQ, we need to know the number of days per year considered in the average daily demand. This could be determined based on the store's operating schedule. Let's assume 365 days per year for simplicity.
Using the EOQ model, we can determine the optimal order quantity that minimizes total inventory costs. The formula for EOQ is:
EOQ = √((2 * Annual Demand * Ordering Cost) / Holding Cost per Unit)
To calculate the EOQ, we need additional information such as the ordering cost (cost to place an order) and the holding cost per unit (cost to store one box of diapers for a year).
By applying the EOQ model, we can determine the most efficient order quantity for Huggers Diaper. This helps in optimizing inventory levels, reducing holding costs, and ensuring sufficient stock to meet customer demand.

b) Revenue function, R(x) = $546x
c) Profit function, P(x) = R(x) - C(x)
d) To break-even, Fixed cost/Contribution per unit
= 13.3 or 14
Explanation:
a) Data and Calculations:
Fixed costs = $945 per week
Total costs = $8,070 per week
Production units = 15 boards per week
Variable costs = Total costs minus fixed costs
= $7,125 ($8,070 - 945)
Variable cost per unit = $7,125/15 = $475
Cost function, C(x) = $475x + $945 = $8,070
Revenue function, R(x) = $546x
Profit function, P(x) = R(x) - C(x)
= $546x - ($475x + $945)
Contribution per unit = $546 - $475 = $71
To break-even, Fixed cost/Contribution per unit
= $945/$71 = 13.3 or 14

The search engine uses the search terms entered by the user and the keywords stated by an advertiser in his/her advertisement and brings forth the matching results based on the keywords.
In the given case, Jennifer limits her audience for an 'all-inclusive vacation to Paris.' So, the correct search term that will match with her keywords in the advertisement will be 'all-inclusive Paris holiday.' This search term will match with the keywords of Jennifer's advertisement.
Thus the correct answer is the last option.
