the correlation between years of education and salary in a sample of 20 people from a certain company is .4. is this correlation statistically significant.

Complete Question:

The correlation between years of education and salary in a sample of 20 people from a certain company is .4. Is this correlation statistically significant at the .05 level?

We accept hence no significant  evidence

Step-by-step explanation:

From the question we are told that

sample correlation n= 20

population correlation  = 4

level of significance

Generally we are task to understand existing difference between  sample correlation and population correlation

Generally null hypothesis  is given by

alternative hypothesis

generaly the mathematical representation of test statics

Generally for table the p value is given by

p value > the null hypothesis

Therefore

We accept hence no significant  evidence

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
