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 and Explanation:
Dr. Jon Kabat-Zinn develops Mindfulness-Based Stress Reduction (MBSR) in the 1970s. It is a healing approach that combines meditation and yoga. The main aim of Mindfulness-Based Stress Reduction is to address the unconscious thoughts, feelings, and behaviors thought to increase stress and undermine your health.
Mindfulness is a practice involved in religious and secular traditions like Hinduism and Buddhism to yoga, but now non-religious people also practice meditation.
In general, Mindfulness-Based Stress Reduction was popularized in the East because of religious and spiritual institutions. On the other hand, West's popularity can be traced to particular people and secular institutions. The secular tradition of mindfulness west has its roots in Eastern religions and traditions.
Most modern Western practitioners and teachers learned about mindfulness in the Buddhist and Hindu tradition.
Answer:
b. Alex's occipital lobe is artificially stimulated.
Explanation:
Alex volunteers for an experiment being conducted by a group of neurosurgeons. As part of the experiment, he is taken to a dark room and a part of his brain is activated with electricity. For a moment, Alex sees flashes of light even though the room is pretty dark because Alex's occipital lobe is artificially stimulated.
Occipital lobe is one of the four lobs in the cerebral complex of brain. It is related to the visual effects in the brain of the mammal. It is also known as the visual processing center. This is reason why Alex saw flashes even though it was dark.
