Which of the following r-values represents the strongest correlation 0.62,0.50,0.32,0.45

0.62

Step-by-step explanation:

We know that when the r value is closer to the absolute value of 1 i.e. either 1 or -1, then it represents that there is a stronger correlation.

The given r-values : 0.62,0.50,0.32,0.45

From all the given correlation coefficient , the r value which closest to the absolute value of 1 is 0.62.

Therefore, the r-value that represents the strongest correlation = 0.62

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
