(a) A researcher wishes to test the performance of two paper shredders, the Stanley and the Bosch, designed for professional use. Each of 10 randomly selected volunteers shredded 100 sheets of paper with the Stanley, and then another sample of 10 randomly selected volunteers each shredded 100 sheets with the Bosch. The Stanley took an average of 203 seconds to shred 100 sheets with a standard deviation of 6 seconds. The Bosch took an average of 187 seconds to shred 100 sheets with a standard deviation of 5 seconds. Assume that the shredding times for both machines are normally distributed with unequal and unknown standard deviations.

(i) Construct a 99% confidence interval for the difference between the two population means.

(ii) Test whether the claim that mean time taken by the Stanley to shred 100 sheets is higher than that for the Bosch is true, using a 1% significance level.

(iii) Explain what would your decision be in part (b) if the probability of making a Type I error were zero? (b) A random sample of 500 observations chosen from the first population gave x1 = 305. Another random sample of 600 observations chosen from the second population gave x2 = 348.

(i) Compute the point estimate of p1−p2.

(ii) Construct a 97% confidence interval for p1−p2.

Create following variables:

Price for a cup of coffee (make it adjustable within the program)

Number of cups (response from User)

Tax Rate in San Diego is 8%. Define 8% as a CONSTANT variable that never changes

Payment Method (Cash, Credit Card, Store Credit, Gold)

Ask the customer for their first name, and store it as a String object.

Ask the customer (by name) how many cups of coffee they would like to order and save that value.

Calculate the Total (# of cups * Price per Cup) * Sales tax

Using the printf, make all currency data printed to the screen display 2 decimal places, and also a '$" sign.

Also use at least one Decimal Format print method .

Using a switch statement on the payment type

If the user entered 'm' or 'M', display "You are paying using money" to the screen.

If the user entered 'c' or 'C', display "You are paying by Credit Card" to the screen .

If the user entered 's' or 'S;, dispay "You are paying with Store Credit" to the screen.

If the user entered 'g' or 'G', display "You are paying with Gold" to the screen.

If the user entered anything else, display "Invalid payment type, no lemonade for you!", and end the program

Using an if statement, If the quantity is less than 1, then display "Get out of my store, you bum!" and exit the program

Using a single if-else-if statement (also called a multi-branch if-else statement)

If the total is less than $10 and the user is paying by credit card, display "Sorry, there is a $10 minimum purchase for credit card"

If the total is between $10 and $100 (including $10 and $100), and display "Thank you, you earned a free glass of Lemonade!"

a. [4 marks]Find Clarrie’s purchase price (per $100 face value, rounded to 3 decimal places) of this Treasury bond, allowing for a 30% tax on interest only, to give a yield of j2 = 3.2% p.a. (net). Draw a cash flow diagram that models this scenario to accompany your answer.
b. [4 marks]Find Clarrie’s purchase price (per $100 face value, rounded to 3 decimal places) of this Treasury bond, allowing for a 30% tax on interest only. The tax on interest is paid one year later (e.g., for the coupon payment at t = 0.5 year, the tax payment will be paid at t = 1.5 years.), to give a yield of j2 = 3.2% p.a. (net).

Its all the question information

A firm manufactures a product in the United States. Its costs of production and shipping are $100. It sells the product in Silliestan for 1000 Zlotys which is equivalent to $500 (2 Zlotys = $1). Costs of distribution and selling in Silliestan are $100 (200 Zlotys) so the firm has a profit of $300. Within the next year, the Zloty is expected to fall from 2 Zlotys to the dollar to 4 Zlotys to the dollar while inflation in Silliestan is expected to be 100%. US costs, in dollars, are not expected to change.

Show all calculations. No points for the correct answers without calculations.

a) Given these expected changes, how many Zlotys will it cost, in total, to make the product in the United States and to sell it in the foreign country? The total costs of manufacture, shipping and sales will be ______________________ Zlotys. 2 points

b) If you sell the product for 1000 Zlotys, how much would your profit or loss be? ________ Zlotys 2 points

c) What other factors should be taken into account when setting a price? Be specific. 1 point.

d) If your company sells the same product in a neighboring country for a higher price, this would give rise to a ____________________ market. 1 point

e) If the foreign country were to ask your firm to take partial payment in a local product, say turnips, this would be an example of ________________________ . 1 point.
