Answer:

The sample mean of the data is:

7.7

Step-by-step explanation:

The sample mean is the sum of all sample observations divided by the number of sample observations.

Let sample mean=x

x=(7 +7 +10 +6 +9 +6 +8 +7.5 +8.5 +8)/10

x= 77/10

x= 7.7

Hence, the sample mean of the data is:

x=7.7

A researcher records the odometer reading and age of used Hondas. What kind of correlation is likely to be obtained for these tw

tresset_1 [31]

Using the concept of correlation, it is found that a strong positive correlation is expected between these two variables.

When two variables are direct proportional, that is, both increase together, there is a strong positive correlation.

In this problem, the older the car, the more it should have traveled, that is, the higher the read on the odometer, hence, there is a direct proportional relationship, which means that the variables have a strong positive correlation.

5/9= 0.555555556

0.55555556*63=35

2/3= 0.6666666667

0.666666667*63= 42
