Question

Transcribed Image Text:Events A and B are two non-mutually exclusive events with the following probabilities
defined:
A.
p(An B') = 0. 13,
p(AU B)' = 0. 41, p(A'n B) = 0.38
(i)
Draw a fully labeled Venn diagram showing the probabilities of all the regions in
the sample space.
Question 4A (cont’d)
(ii)
Determine the following probabilities using the addition and conditional
probability rules:
p(A' U B)
p(A|B')
В.
A deck of 10 cards marked 2, B, B, 5, 5,5 8, D, D and F, are to be arranged on the
table.
(i)
If you were to select 5 cards from the deck, what is the probability that all 5 cards
are numeric cards?
(ii)
What is the probability of having an arrangement where the B's are in the first
and the last position?
A study was conducted to investigate the relationship between a person's hand strength
and its stretchability. A random sample of 20 students was selected and their hand
strength and how much they can stretch was measured.
Their hand strength values range from 1 – 10 points, while the stretchability values
range from 1 mm – 15 mm.
C.
The results are summarized as follows:
Ex = 109, x? = 787, Ey = 143, y² =
1575,
ху 3D 1036
(i)
Calculate the correlation coefficient of the two variables. Hence, comment on the
relationship between hand strength and stretchability.
(ii)
Write the equation of the linear regression line of the stretch on the hand
strength?
(iii) Predict the stretch of a person who has a hand strength of 12. Is this prediction
reliable? Explain your answer.
