1 answer:
Answer: 0.753.
Step-by-step explanation:
The value of the correlation coefficient is denoted by 'r'. It is used to describe the strength and direction of the relationship between two variables.
Given: The relationship between the number of hours a person practices a task and the time it takes them to complete the task is calculated to have R-sq = 56.7%.
= 0.567
Then,
Hence, the value of the correlation coefficient is 0.753.

0.0786
Step-by-step explanation:
It is given that Bartholemew had drawn the replacement of 160 tickets.
There are five tickets = [0, 0, 0, 1, 2]
Now we need to find the estimate of the ticket that has 1 on it and it turns up on the 32 draws exactly.
Since the probability of the drawing 1 out of 5 tickets is given by,
So the binomial with the parameter of n = 160 and p = 0.2, we get
P (it turns up on exactly 32 draws) = P(X = 32)
Therefore,
= 0.0786
