Intended audience are the passer-by and those who stumble upon it online and children and those who practice them e.g a poster about what happens to those who smoke.
Like I said to educate and teach on the dangers of doing them.and also for awerness
Explanation:
Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r

x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0

r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
Answer: Assurance
Explanation:
Five service quality are the characteristics that are used for measuring the quality of service through evaluating responsiveness, assurance, tangibility, empathy and reliability.
According to the question, students are more focused on assurance factor out of all the service quality factors because they expect a secure advise.
The quality of assurance imparts trust and confidence in the students and make them believe that the advise given by Professor Guillory is good .
