SOLUTION 7

Which of the following measures the degree of linear association between two variables?

a. covariance

It enables us to find the degree of linear association between two variables. Further used in the calculation of correlation coefficient

QUESTION 8

If the sample size becomes larger, to which distribution does the sampling distribution of the sample mean converge?

a. Normal distribution.

According to the Central limit theorem as the sample size becomes larger the distribution of the sample mean converges to the normal distribution.

QUESTION 9

Which of the following means an estimate of a population parameter that provides an interval of values believed to contain the value of the parameter?

b. Interval estimate.

QUESTION 10

In hypothesis testing, which of the following means the tentative assumption about the population parameter?

c. Null hypothesis

correlation measures the degree to which two variables are related to one another. Here are the definitions of the three possibilities: Positive correlations: In this type of correlation, both variables increase or decrease at the same time. A correlation coefficient close to +1.00 indicates a strong positive correlation. Negative correlations: This type of correlation indicates that as the amount of one variable increases, the other decreases (and vice versa). A correlation coefficient close to -1.00 indicates a strong negative correlation....

  In this question, we will formulate a measure to quantify the level of association between the two categorical variables. Such a measure is often used in a statistical test called Chi-square test for assessing whether there is an association between two categorical variables. This question is also used to motivate the learning of independence and to connect the concept back to what we have learnt in the course.Let's revisit the example we have looked at in the course. How...

Information about an association between two interval-ratio variables is presented below. The association is between “the hours of screen time per day” (Y) and “years of schooling” (X). A measure of the overall association is given as well as the specific components of the OLS model. The OLS model estimates the effect of education (X) on the hours of screen time per day (Y).
