basketball coach asks half his players to stretch before each game; the other players do not stretch. after a month of games, she analyzes their playing stats. she concludes the stretching improve their performance on the court. how can the coach test the means to be sure the results not likely to happen by chance? (3 points)she can pick players at random and analyze their playing stats without calculating means. she can analyze the two groups by calculating the means and the difference of the means. she can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means. she can pick the players she wants to analyze based on the best stats.

C.  She can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.

She can re randomize the results by separating the two groups randomly, then calculate the means and the difference of the means

Step-by-step explanation:

For calculating the mean, we sum the values and divide the sum by the number of cases.

Here the coach already divided the players in 2 groups- one who stretches and one who don't and wants to conclude at the end. So, the best possible answer is - She can re randomize the results by separating the two groups randomly, then calculate the means and the difference of the means.

answer: i oofed

step-by-step explanation:

oofed=wow

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
