Ipatiy [6.2K]

Answer:

a) r = 0.974

b) Critical value = 0.602

Step-by-step explanation:

Given - Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both test and the results are give below

Test A | 64 48 51 59 60 43 41 42 35 50 45

Test B | 91 68 80 92 91 67 65 67 56 78 71

To find - (a) What is the value of the linear coefficient r ?

(b) Assuming a 0.05 level of significance, what is the critical value ?

Proof -

r = 0.974

Critical Values for the Correlation Coefficient

n alpha = .05 alpha = .01

4 0.95 0.99

5 0.878 0.959

6 0.811 0.917

7 0.754 0.875

8 0.707 0.834

9 0.666 0.798

10 0.632 0.765

11 0.602 0.735

12 0.576 0.708

13 0.553 0.684

14 0.532 0.661

So,

Critical r = 0.602 for n = 11 and alpha = 0.05

Here is my question please answer and give a good explanation: Which expression cannot be used to calculate the total amount pai

Ierofanga [76]

I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
