2.3.25 Underage drinking, Part I:Data collected by the Substance Abuse and Mental Health Services Administration (SAMSHA) suggests that 69.7% of 18-20 year olds consumed alcoholic beverages in 2008.

(a) Suppose a random sample of ten 18-20 year olds is taken. Is the use of the binomial distribution appropriate for calculating the probability that exactly six consumed alcoholic beverages?

Yes, there are 10 independent trials, each with exactly two possible outcomes, and a constant probability associated with each possible outcome

No, the normal distribution should be used

No, the trials are not independent

No, this follows the bimodal distribution

(b) Calculate the probability that exactly 6 out of 10 randomly sampled 18- 20 year olds consumed an alcoholic drink? (please round to four decimal places)

(c) What is the probability that exactly four out of the ten 18-20 year olds have not consumed an alcoholic beverage?(please round to four decimal places)

(d) What is the probability that at most 2 out of 5 randomly sampled 18-20 year olds have consumed alcoholic beverages?(please round to four decimal places)

(e) What is the probability that at least 1 out of 5 randomly sampled 18-20 year olds have consumed alcoholic beverages?

(please round to four decimal places)

3.2.38 Baggage fees:An airline charges the following baggage fees: $25 for the first bag and $35 for the second. Suppose 54% of passengers have no checked luggage, 34% have only one piece of checked luggage and 12% have two pieces. We suppose a negligible portion of people check more than two bags.

a) The average baggage-related revenue per passenger is: $(please round to the nearest cent)

b) The standard deviation of baggage-related revenue is: $(please round to the nearest cent)

c) About how much revenue should the airline expect for a flight of 120 passengers? $(please round to the nearest dollar)

Question 6 1 pts Benny operates a gardening service to customers. The services provided include mowing, fertilising, weeding, pruning, garden design and a spring tidy up. The diagram below is used to describe part of the database model used by Just Benny. Refer to the diagram and indicate which of the following statements is TRUE A ' 0 Each service item is for only one customer only 0 An invoice detail is for many customers 0 An invoice can have many invoice details 0 Many customers are included in the one invoice detail The owners of an e-business have been successful in selling fashion products but are now venturing into another domain. Knowing that the impact of advertising on profit cannot be overemphasized, they are interested in determining the right amount to allocate to advertising for the new business. Based on a monthly report from the fashion e-business, a regression analysis of monthly profit (in thousands of dollars) on advertising spending (in hundreds of dollars) produced the following results: slope y-intercept 1.34 2.451 0.7372 where y = profit (in $1000s) x = advertising spending (in $100s) a. State the least-squares regression line for the data. 0 + 0 x b. Interpret the value of the slope as it relates to this problem. For every $1 increase in advertising spending, there is a $1.213 increase in profit. O For every $100 increase in advertising spending, there is a $1,213 increase in profit. O For every $100 increase in advertising spending, there is a $121.3 increase in profit. O For every $1,000 increase in advertising spending, there is a $121.3 increase in profit. c. Compute and interpret the coefficient of determination. R- = Round to 4 decimal places d. Predict the monthly profit for a month when advertising is $2,200. $0.00 Round to the nearest cent SProblem 4 (10 points) (a) Pioneer Advertising purchased advertising supplies costing $40,000 on October 5. Assuming that it paid with cash, prepare the journal entry to record the purchase of the supplies, b) An inventory count at the close of business on October 31 reveals that $15,000 of the dvertising supplies are still on hand. Prepare the adjusting journal entry on October 31.Ashley's company makes office equipment for both personal home use and office use.
