3. A personal trainer claims that their exercise programme will lead to a re- duction in weight. The weight in kg of each of 10 participants was measured before and after the programme, denoted X; and Y; respectively. Let D¡ be the difference D; = Xi – Yị. The following information is available: EDi = -31.71 and D; = 120.358. (a) Carry out an appropriate test on the Personal Trainer's claim.

Gasoline is to be stocked in a bulk tank once at the beginning of each week and then sold to individual customers. Let Y, denote the proportion of the capacity of the bulk tank that is available after the tank is stocked at the beginning of the week. Because of the limited supplies, Y, varies from week to week. Let Y, denote the proportion of the capacity of the bulk tank that is sold during the week. Because Y, and Y, are both proportions, both variables take on values between 0 and 1. Further, the amount sold, y,, cannot exceed the amount available, y,. Suppose that the joint density function for Y, and Y, is given by Į 3y,, os y2 s y, s 1, f(Y1, Y2) = elsewhere. A sketch of this function is given below. f(Yy» Y2) 3 - 1 (a) Find (Round your answer to four decimal places.) (b) Find the probability that the amount sold is less than one-eighth the amount purchased. (Enter your probability as a fraction.)

3. Create the following calculated columns. a) In I4, and J4, use a VLOOKUP function that will look up the Product Price and Product Cost based on the Product Sold column which lists an ID number. [Hint: The Product Table sheet lists the Price and Cost] If any error messages appear, check the Range Lookup. b) In K4, use a formula to calculate Profit. Hint: Profit =(Product Price-Product Cost)*Units Sold 4. Format columns I, J, and K as currency with two decimal places. 5. Make a copy of the Sales sheet and rename it Online Sales by Date.

In a recent year, a research organization found that 487 of 806 surveyed male Internet users use social networking. By contrast 619 of 919 female Internet users use social networking. Let any difference refer to subtracting male values from female values. Complete parts a through V below. Assume that any necessary assumptions and conditions are satisfied. Find the proportions of male and female Internet users who said they use social networking. A. What is the difference in proportions? B. What is the standard error of the difference? C. Find a 95% confidence interval for the difference between these proportions.
