The managers of a brokerage firm are interested in finding out the effects of number of new clients that a broker brings into the firm on the sales generated by them. They sample 10 brokers and identify the number of new clients they have enrolled in the last year and their sales amounts in thousands of dollars. These data are presented in the table that follows:
Broker Clients(X) Sales(Y) Calculation shows that
1. 27 52 n=10 2. 11 37 X = 260 3. 40 64 Y= 480 4. 33 55 X2= 7594 5 15 29 Y2= 24276 6. 15 34 XY =13377 7. 25 58 SSX =(X-Xbar)2 =834 8. 36 59 SST=(Y-ybar)2 = 1236 9. 28 44 SSE = (Y –Yhat)2=271.241
10. 30 48 (i) Assuming a linear relationship, what is the prediction for the amount for sales (in $1,000s) for a person who brings 25 new clients into the firm? (ii) Calculate the standard error of estimate and interpret the result. (iii) Test at 5% level of significance that the number of new clients that the broker have enrolled in the last year is significant predictor of their sales amount.

essay about the impact of lack of resources in school?
The learning process of pupils is significantly aided by the use of resource materials such as charts, posters, whiteboards, blocks, cards, clay, crayons, and chalk, among others.
The effect of a lecture may be significantly increased by using resource materials appropriately. The availability of a wide range of educational resources can spark enthusiasm and actively engage students in the study of mathematics (Herward, 2009). Because these are fundamental elements that can help students achieve academic success, it also increases the efficacy of schools.
The appropriateness, sufficiency, and efficient use of the resources at hand determine the information that is learned in an educational setting. Teachers' attitudes and methods of instruction have the potential to affect pupils' attitudes.
