I think A? I think this because 0.5 isn't on that chart, and 10,10 is. 10 10 is the only one that matches up

Answer:

The correct option is A.

Step-by-step explanation:

From the given scatter plot in is clear that the coordinate pairs of points are (1,1.5), (2,2), (3,3), (4,4), (5,6), (6,6.5), (7,7), (8,8), (9,9), (10,10).

If a line best represents the data, then that line is called line of best fit. The line may or may not passes through all the points.

The main objective of this method is to minimizes the squared distance of each point from the line of best fit.

Draw a line of best fit as shown below.

From the graph it is clear that the line of best fit passes thorugh the points (0,0.5) and (10,10).

Therefore the correct option is A.

Stephen Curry's Free Throws As we see in Exercise P.37, during the 2015-16 NBA season, Stephen Curry of the Golden State Warrior

Reil [10]

Answer:

A) $P(X=x) = \binom{2}{x}.(0.908)^x.(0.092)^{2-x}$

B) Mean = 1.816

Step-by-step explanation:

We are given the following information:

We treat Stephen Curry making any given free throw as a success.

P(Stephen Curry makes any given free throw) = 0.908

Since the probability for the free throw is equal for each trial and free throws are independent.

Then the number of free shots follows a binomial distribution.

A) Probability distribution

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Here n = 2, p = 0.908

$P(X=x) = \binom{2}{x}.(0.908)^x.(1-0.908)^{2-x}\\\\P(X=x) = \binom{2}{x}.(0.908)^x.(0.092)^{2-x}$

Now x can take values 0, 1 , 2

Putting values, we get,

$P(x = 0) = 0.008464\\P(x = 1) = 0.167072\\P(x = 2) = 0.82446$

B) Mean of X

$\mu = np = 2(0.908) =1.816$

Thus, the mean number of free shots made by Stephen Curry is 1.816
